Hey Louis and Dave, I own a rework/solder station and have the same issue with flickering (fluorescent) lights in my workshop. I did some investigating with a power meter and in my case at least it is caused by the logic board modulating the heating element on/off in short pulses once it is up to temperature to keep it at temp. Taking the heater off the stand also causes my lights to dim, placing it back in the holder fixes that issue immediately (while the fan is still cooling it down). The entire workshop is on one breaker, separating the lighting from the outlets at the breaker panel should solve the issue.
yea right they would do all talk no work like always... these dudes everyone look up to need to learn better soldering skills they are both horrible with soldering iron imho.

Really surprised to see a brushless motor in there. How would conducted or radiated noise cause lights to flicker? It's obviously just the current draw when the heater turns on & off
mikeselectricstuff Exactly, I have much weaker hot air station which does the same. It uses a TRIAC in leading edge phase fired controller circuit, which is the source of that flicker.
Yes, Louis needs to not run that on the same circuit as the lights. When I'm down in some old cellars doing my work with a 2kW hot air gun, the lights flicker like crazy. Old wimpy wiring and long runs from the breaker panel tends to do that to you.
Louis' advice: Wait for the chip to dance (move) before you remove it. I made the same mistake until I saw Louis do it. I have learned loads from his content You didn't seem to like the angle of the fan, even though you didn't criticize it. I think I see the method behind the madness of the designers. I think the placing of the fan enables it to suck cold air over the components that get hot before it gets heated and blown out of the nozzle at a PC board. Brilliant ingenuity. I take my hat off to them. It is always a pleasure to watch somebody who knows what he is talking about, and it is a pleasure watching you. Keep it up mate :)
Once again sir you hit on ALL the key points that allow me to justify purchasing a tool like this. So entertaining AND informative. Thank you again Dave! You are just flat out AWESOME!
Pretty sure Louis' issue is that a US circuit is only 15A @ 120V, so 1000W is a pretty good chunk of that. The big disadvantage of 120V and small (14ga / 2sqmm) wire. Not uncommon at all to see lights dip here in North America when a bit load is switched in
It could be, but a JBC JT-A at full power causes zero flickering. Maybe the Quick is more powerful, but I don't think it is *that* more powerful. As much as I love my Quick I have to acknowledge that the $1200+ price difference comes from cheaping out on the power supply.
Boffin A typical 120V US circuit may be either 15A (1800W, #14 copper minimum) or 20A (2400W, #12 copper minimum), both are quite common though in very old structures the 15A circuit was much more typical since in the first half of the 20th century a typical household load consisted of lights, a radio, later a TV, and the occasional clothes iron or vacuum and that was about it outside of the kitchen. However, the tendency towards flicker really depends a lot upon where in the AC cycle the heating element is being powered on. I would imagine they are using a random phase triac driver, which means you can be switching on a high powered heating element right at the AC peaks with fair regularity and if your circuit is already loaded down or has a fairly long run back to the mains panel then you can get noticeable flicker, particularly with fluorescent and LED lighting. You might well be able to get away with swapping the random phase triac driver for a zero-crossover driver and resolve the flicker issue so long as long as the temperature regulation loop is not adversely altered.
I bought one of these soon after Louis's review. It is indeed very good. Compared to my existing rework station no contest for desoldering large components and BGA's and such there's simply no contest. Also Louis, is a great channel. He's a good guy and for someone who's much older than him I've gotten a few life lessons too. I like his cats too :)

Hot air was one of my special skills!! Pre-heat bed and hot air gun and I could rework QFD devices, and BGA devices by hand, and I was tagged as the "expert" in my group. It can be a really really TRICKY skill! SOT packages, 0201 SMDs, of course 0402, 0603 and larger got to be a piece of cake.
The trick with these is the careful application of heat and not damaging all the surrounding parts. I generally pre-heat the whole board slowly before going for the lift. I also have high temp silicon sheets that I use to mask the target area. It does no good if you damage the PCB or other components. Liquid or gel flux is critical IMHO.
Quick seems to be well distributed in Poland. I had to buy mine from there to France for around 250€. There was other offers in Europe but not for the beefier 861DW variant.
When you turn the holder around, you can pull the nozzle and have it cached in the cup. What for not having hot metal things rolling all over your bench. ;)
I love Louis 's channel, great life lessons and lessons on board level smd repair work all round. ......... also time is money, the quick 861DW will earn back itself in a week if you are a professional.
Hi great video. Switching between Celsius and Fahrenheit can be achieved by pressing both the ch2 and ch3 buttons for 3 seconds. (Sound can be toggled on/off by pressing ch1 and ch3 for 3 seconds)
@@mitchcm that's a bummer! I've never used the 881d. I only have the 861d model. (Also I wrote my original comment wrong; it is ch1 and ch2 to toggle sound)
Probably someone already commented on this, but it seems there are two models, the 861DW and the 861DE. The DW only goes to 120 l/min and the DE is the one that goes up to 200 l/min. So the display is actually indicating the air flow in l/min.
Not even watched it yet, but thank you Louis been waiting for this since he mentioned he sent you one. I have been trying to get a filter right to kill the feedback that messes with the lights since I got mine.
The motor may look 'wimpy' but you'd be surprised how much power a small brushless motor can deliver. For a robotics project we used a brushed motor of about 15W to drive a dribbler system to move a ball. This motor was replaced by a tiny brushless motor from maxon motors (i believe it was the EC max 30) which was just 30mm x 62mm, a lot smaller than the original 15W brushed one, yet put out an incredible 60W of power.
This is the actual motor used; www.wonsmart.com/English/Product/0586241350.html It's a torquey little brute, 17,000RPM unloaded speed, 8K full load delivering a max torque of 58 mN-m. Real ball bearings. 3 hall effect sensors, 3 phase. 110-ish watts under full load. Very narrow and light spinning mass for ease of balance and quietness. Excellent choice. Not a cheap motor either,.
True, for quality motors you have to spend big bucks, but its worth it. Next to clearly better performance and being quiet, they last a loooot longer in my experience.
One correction, airflow on the DW model is only 120 (like it says in the display). The DE model of the 861 series is a 200 L version (and 1200 watts instead of 1000 on the DW). And on the DE the LCD setting goes to 200 (as expected).
400C at full airflow seems a bit excessive but I can't fault the speed, especially for the big FETs. I've used whatever hot air station Sparkfun sells before but this one definitely seems worth the added cost.
I bought an 858D. But I bought it only for heat shrink tubing. I’ve got some good guns, but for smaller wires and such, they’re too big and overkill. Never tried it on surface mount components. It does come with several sizes of nozzles. The temp setback does work. Also, I got it on eBay for a bit over $40, shipped. Seriously, for $40, it’s pretty good. This model is available from a number of different vendors with the same, or similar look, with different names.
@@nombinator lol not sure how the nation that invented the grid has an odd custom voltage relative to later adopters. As for less subjective I seem to recall 50hz is a bitch for motors. Having watched enough LR I'd guess he chose to use recycled soda cans instead of copper wire 😂 220 easier to get a lethal hit from too no? Simple i=e/r
@@johnw1385 240v means lower current for the same power, less voltage drop for a given conductor size or cheaper conductors for a given voltage drop. Fatalities in modern GFCI protected installations are very rare.
I think if you put a scope on the heater you would see it switches fairly slowly, that causes the lights flickering... just the branch circuit voltage drop due to the heater load. I get lights flickering with a temp controlled heat gun when the lights are on the same breaker. Louis probably has the same thing, needs isolated circuits for lighting vs high power equipment. But, as a renter, doing electrical upgrades is just donating $$$ to the landperson...
This right here. I have a different SMC rework station and when it switches the heater on/off it causes heavy voltage drop on the bench circuit, sometimes fast enough to get a nice flicker going on the bench lights. It is far worse on a 110v system with that 1kW load.
micksam7 Bingo. It’s brutal on a normal 110v circuit with any other load on it. It does proper zero-voltage AC chopping (watch Louis’s teardown; they get the scope on it. It switches just like the Hakko or any other high end unit, it’s just much higher current) and basically everything else right, but there’s only so much it can do with weak sauce US mains circuits.
I came here to see the 858d in action because I just bought one and wanted to know how it would stack up against a professional machine. Thanks for the video. It really helped and I think I can do my amateur stuff with the 858d just fine. I just need to be a bit more patient. Great stuff!
Dave, shouldn't that stand be used the other way around? Both for the attachment removal (so the attachment falls into the cup below) and for the weight of the cable pulling the hot air iron into the stand instead of pulling it off of it like in the video at 4:50. 🧐
I also have this Quick Station. There is nothing in this price range that can compare. Hakko and Weller is almost 3 times the price of the quick. I have mine for almost half an year and I'm still very impressed. Unfortunately mine has a "beeping" noisy motor with high frequency sound -.- but beside of that if you searching a hot air station right now. There is no way around the quick
@23:00 You need some Ceramic Tweezers dude. Nice device. As a hobbyist I'll keep on with my UYUE 8586 but if it stops working the Quick will be on the wish list. Nice video.
I bought a Quick 861DA about 8 weeks before Louis got his... i'd been deliberating on it for weeks. Glad I made the right choice. Wholly justified by your review too Dave. Odd thing is I get the same light flicker as Louis.. keep up the good work :)
I'd guess the flickering lights is from the heating element. When it's cold from being off or cooled down from being in the rest, it's going to surge the element at full power to bring the heat up as quick as possible, then likely PWM the power to the element to maintain heat. I see the same with my cheapo heat gun like the one you have. My entire bench is on an APC 1500va SmartUPS. When the heat gun 1st comes in it nearly maxes out the load the UPS can take for a few seconds, then it levels out to a much lower power draw depending on the temperature set
Hello, you seem very knowledgeable of this product. I have this station as well and it's no longer heating properly. I replaced the heating element, and it did not fix it. It's barley heating at all. What is the most likely part that's causing it to not regulate the temp?
Questions, would the fact that it is higher temp inside of the Nozzle have anything todo with the loss of heat as the air travels to the component? I am looking at get a rework station. Never used one.
32:11, not You mistake, just use FLUX easy to remove after desolder process and vacuum tweezers to lift big BFA chips. Good to use termo sensor and best way to use preheater set to 100-150 st C. No to fast heat or internal silicon can crack.
If I understand correctly the 1meg ohm resistor from line to ground, supposedly for noise is something which was done to audio equipment in the 1960s-1970s. It creates a live chassis situation. I'd snip that out.
You have misunderstood the video. This is a high value inline resistor used to safely ground the earth strap socket at the back of the chassis. It isn't connected to the live supply in any way.
I got mine QUICK 861DW a few days ago. For my unpleasant surprise, the airflow controll on this brand new unit seemed to be stuck on max. level. If I went below 112, the fan just stopped and a few beeps later it showed "ERR" message on the display. Upon closer inspection of the motor driver board, I noticed that the R59 timing resistor is simply missing. Since my attempts to measure the value of the C53 were unsuccesfull, I just assumed it to be 10nF. According the MC33035DW datasheet, fig.1, with 10nF cap @ 25khz, the timing resistor should be around 4,7k. so I teporarily soldered one in between pins 8 and 10, and voila...no more error messages and the airflow controll appears to be working just fine too. But just in case, could someone please look at the original value of the R59 on the motor drive board and post it here?? thanks very much...
As for hacking it, I have replaced the firmware of a solder station with proper PID control as well as zero cross switchin on the triac. Also display of the real temperature vs. the set. Note that afaik the atten shows the real temperature only when it is in power down mode, when it thinks its up to temperature it never shows any overshoot, but when you then put it down, it suddenly does. Regarding the loctite on the ground screw, I have seen some where this caused it to have no contact as it crawled in between.
The quick uses a remarkably well-tuned PID for temperature control. Dave's experimental methodology (sort of vaguely stuffing a thermocouple bead into the nozzle) is, well, poor. I set up a proper jig to hold the handpiece with the thermocouple in free air 5mm from the nozzle outlet so I could test/offset it properly shortly after I got it, and aside from the time taken to bring the nozzle up to temperature, the output is astonishingly accurate. Within ~5 degrees for the whole range, getting more accurate as the temperatures got hotter (up to the limit of my thermocouple anyway) So when he says 'it must be lying about temperature, it can't be that stable' I believe he is mistaken.
Seriously Dave you're at one point suggesting that radiated EMI from a bench top device like this might cause the lights in a workshop to flicker?!?!? Too much coffee today?
I just picked this up as a side fun project to learn. I can't seem to desolder smd leds for some reason. Either I'm not getting it hot enough or I am afraid of torching stuff..lol this is my first time and I have mulitple PCB's that are dead and just practice on. I can't seem to get the hang of it yet. I know how to solder normally but totally new to hot air rework stations.
My brother in-law used to work at the Adelaide Showgrounds setting up and repairing power distribution points for show rides etc. They commonly referred to using two cable ties to secure flexible leads within an enclosure as 'Carnie Proofing'. Apparently the show-ride operators, or 'Carnies', had a reputation of being a little rougher than most with flexible power leads, often driving off with things still connected. Two cable ties = 'Carnie Proof'
I was using a heat gun in my server room to test some temperature alarm points and noticed the lights flickering too, I think it's because these type of devices just modulate on/off instead of just adjusting the voltage to the element.
Compare Quick 861DW with Best BST-863, and with NT 762E, low price product to one category. Quick 861 DW and Best BST863, inside the same, the parameters are the same, but the price is lower twice at BST 863. Do a comparative review.
Hall Effect type thing. I inherited mine without the stand so was unaware they auto switch off when in a stand. Drove me nuts while trying to replace the voice coil on a big woofer. Damn thing kept turning off when ever I brought it near the speaker. Had me stumped for awhile.
The Quick TS1200A Solder station is a perfect mate to this hot air station. It's a complete beast @ 120 Watts. I just posted a Quick / Hako comparison video on my channel.
Wait... Dave showed 200L/min for the quick - but all shops and sources i find advertise it as 120l/min just like the atten?! Okay the Quick UI also shows 1-120 airflow... so nothing about 200 - so is the quick really better than the atten?
Yes, he was wrong about the 200. Is it better,? Ot depends on what you use it for. It does heat up faster with the 1000 Watt heater, has a better whirlpool 3 phase brushless motor and motor ESC controller board, proper mains filtering, program able to switch faster between ore-set modes (most hobbiest might not benefit from this, but can save time in production or repair shops) ground strap plug in the back if you don’t have a ESD mat (probably should still have one for professional work) and I think the Quick will last a longer longer for the money. Most I’ve seen sold are 2 year and 3 year warranty. But it mainly depends on what you really use it for, how often, all day at work or hardly used as a hobby.
Gadget Review Videos Ok, overall the quick sounds higher quality - what I am still confused about: if both have the same airflow: how can the atten perform so much worse (slower desoldering time) - I mean the temp is regulated so more power does not give you an advantage if you have the same airflow?
It's hard for me to believe any of these tell the truth. My WHA900 feels like it has the same max airflow as the 861DW and it was rated to 50L/minute. Anything that advertises over 25L/minute should be good. It's the crappy hot air "pencils" built into 3-in-1 stations that are usually garbage, limited to 5-15 L/minute. Unable to do anything worthwhile with those and they often cost as much as a dedicated station.
Funny how a review of an expensive hot air station actually shows that the cheap Atten is more than adequate for my needs. Added that one to my wishlist. 🙂
@@bobweiram6321 Funny how you assume I can't tell the difference with absolutely nothing to back up that assumption. If your soldering is as bad as your reading, you'd better stay away from electronics completely.
When it gets hot those nozzles have a tendency to fall out I ended up drilling a small hole in the collar and tapping it to put a small screw to retain the nozzle
I'm a behringer at air soldering. Can I get some recommend tutorial videos for assembling PCBs (not rework)? I'm mostly doing 0805 and 0603. Pcb heater plate essential, how to spread solder paste etc?
QUICK 861DW professional mobile phone repair and repair station, using brushless vortex fan, adjustable air volume, wide range, can be used for a variety of purposes. The system has the function of automatic cooling of air volume, which prolongs the life of heating elements and protects the hot air handle.
I've read in reviews that some of these 858D units are dangerously wired. Are the gun shaped, paint stripper type guns worth considering for someone on a budget? Or completely unsuitable?
I've got an identical unit as the Atten but called Hiyko. It doesn't display the overshoot of Dave's Atten and doesn't give me problems with the sleep detection. Could just be smoothing the temp value more or maybe improved control firmware?
honestly that temp memory feature on the quick is useful. I have an older cheaper model and switching between desoldering temps and lower temps for just melting stuff or shrink is a pain, many of times have I grabbed mine without thinking just to hit some heat shrink and its set at 400C
All reviews said cheap blower not so good and only for ocasional work, but thats what i needed so i bought it for 50 dolars. Impressive, especially for the price. Now your review is first where i see how capable cheap one is. True its slower, but with so much headroom on the temp i dont bother i will be needing more expensive any time if ever. And one if best parts with my cheap station is it stacks perfectly with my other tools!
I've used Aoyue 968 for the last 11 years. Had to replace the soldering iron part of the station, but as for that, it's been a trooper. My only complaint is there is some radio noise around 150Mhz and again at 155Mhz that interferes with my testing of radios. I usually have to program the radios to something else so it doesn't get interference.
Here's my thinking.... You set the minimum temperature needed for the desolder and then adjust the power/speed with airflow, since the the heating power carried by the airstream is depended on temperature and airflow on equal proportion.
Upon rewatching, by far the best part of this video is the enthusiasm Dave shows at removing the Vanta. I love it!!
So enthusiastic it seems, I lost my balls.
It's OK Dave, Louis is always misplacing his balls :)

Thought the same. "classic Dave, puts the word "quick" in a 30+min video" :D
I've had mine for several months now and it's great!
The trick with these is the careful application of heat and not damaging all the surrounding parts. I generally pre-heat the whole board slowly before going for the lift. I also have high temp silicon sheets that I use to mask the target area. It does no good if you damage the PCB or other components. Liquid or gel flux is critical IMHO.
KAPTON TAPE FTW!
Kriss Olshaq I use Kapton tape as well, but I also rather like the idea of using silicone sheets, so I may have to give that a try one of these days.
I use piles of Kapton tape as well. The silicon, in many cases, is easier to just flop a strip or donut shaped piece on top.
Dave and Louis are both awesome. It's nice to see some collaboration between them.
That "Quick" unit is very nice. A while back I picked up an 898D unit which I like very much, I stole it for $45.00 shipped.
Quick are the choice of Polish professional repair businesses for years now.
Quick seems to be well distributed in Poland. I had to buy mine from there to France for around 250€. There was other offers in Europe but not for the beefier 861DW variant.
@@nombinator bst 868 its better than quick 861dw
When you turn the holder around, you can pull the nozzle and have it cached in the cup. What for not having hot metal things rolling all over your bench. ;)
Neat that Louis sent you this
I love Louis 's channel, great life lessons and lessons on board level smd repair work all round. ......... also time is money, the quick 861DW will earn back itself in a week if you are a professional.
First off. Shout out to Louis and Dave, both excellent youtubers in their respective categories!
Hi great video. Switching between Celsius and Fahrenheit can be achieved by pressing both the ch2 and ch3 buttons for 3 seconds. (Sound can be toggled on/off by pressing ch1 and ch3 for 3 seconds)
This doesn't work on my 881D
@@mitchcm that's a bummer! I've never used the 881d. I only have the 861d model. (Also I wrote my original comment wrong; it is ch1 and ch2 to toggle sound)
Probably someone already commented on this, but it seems there are two models, the 861DW and the 861DE. The DW only goes to 120 l/min and the DE is the one that goes up to 200 l/min. So the display is actually indicating the air flow in l/min.
Not even watched it yet, but thank you Louis been waiting for this since he mentioned he sent you one. I have been trying to get a filter right to kill the feedback that messes with the lights since I got mine.
The motor may look 'wimpy' but you'd be surprised how much power a small brushless motor can deliver. For a robotics project we used a brushed motor of about 15W to drive a dribbler system to move a ball. This motor was replaced by a tiny brushless motor from maxon motors (i believe it was the EC max 30) which was just 30mm x 62mm, a lot smaller than the original 15W brushed one, yet put out an incredible 60W of power.
This is the actual motor used; www.wonsmart.com/English/Product/0586241350.html
It's a torquey little brute, 17,000RPM unloaded speed, 8K full load delivering a max torque of 58 mN-m. Real ball bearings. 3 hall effect sensors, 3 phase. 110-ish watts under full load. Very narrow and light spinning mass for ease of balance and quietness. Excellent choice. Not a cheap motor either,.
True, for quality motors you have to spend big bucks, but its worth it. Next to clearly better performance and being quiet, they last a loooot longer in my experience.
I have one, I thought for a long time about what to buy, but this was the best choice, I worked everywhere Quick 861DW slow heat accuracy scrap!
Yay, Dave! Atten consumes 280w and delivers 28l/m. It is standart blower fan, equipped in most of chinese soldering stations.
One correction, airflow on the DW model is only 120 (like it says in the display). The DE model of the 861 series is a 200 L version (and 1200 watts instead of 1000 on the DW). And on the DE the LCD setting goes to 200 (as expected).
861DW has 120l/min, Atten I think only has 24l/min.
400C at full airflow seems a bit excessive but I can't fault the speed, especially for the big FETs. I've used whatever hot air station Sparkfun sells before but this one definitely seems worth the added cost.
I have the sparkfun station & use it for repairs. Gets you there, cost me 200 plus COD charges in Canada.
I bought an 858D. But I bought it only for heat shrink tubing. I’ve got some good guns, but for smaller wires and such, they’re too big and overkill. Never tried it on surface mount components. It does come with several sizes of nozzles. The temp setback does work. Also, I got it on eBay for a bit over $40, shipped. Seriously, for $40, it’s pretty good. This model is available from a number of different vendors with the same, or similar look, with different names.
It's great to see collaborative youtubing. Well done sir Dave!
My 858D has held up for 3 years now its not bad for hobbyists i've used it a fair bit with no problems
Louis's mains just can't handle heater consuming that much, it is not EMI. He needs better wiring.
Alex Taradov He leases. Any improvements he loses when he goes.
Yes, I know. And he is going to be kicked out of the place at the end of the lease. All I'm saying is don't overthink it, the reason is simple.
Is Louis in 220/230 V mains or that ugly 110 V US custom mains voltage ? That could be part of the answer.
@@nombinator lol not sure how the nation that invented the grid has an odd custom voltage relative to later adopters. As for less subjective I seem to recall 50hz is a bitch for motors. Having watched enough LR I'd guess he chose to use recycled soda cans instead of copper wire 😂 220 easier to get a lethal hit from too no? Simple i=e/r
@@johnw1385 240v means lower current for the same power, less voltage drop for a given conductor size or cheaper conductors for a given voltage drop. Fatalities in modern GFCI protected installations are very rare.
I usually give the reworked part a slight poke with tweezers to make sure that it reflowed, then I lift the part.
A really nice hack would be getting cold air if you press temp up and down at the same time
I think if you put a scope on the heater you would see it switches fairly slowly, that causes the lights flickering... just the branch circuit voltage drop due to the heater load. I get lights flickering with a temp controlled heat gun when the lights are on the same breaker. Louis probably has the same thing, needs isolated circuits for lighting vs high power equipment. But, as a renter, doing electrical upgrades is just donating $$$ to the landperson...
This right here. I have a different SMC rework station and when it switches the heater on/off it causes heavy voltage drop on the bench circuit, sometimes fast enough to get a nice flicker going on the bench lights. It is far worse on a 110v system with that 1kW load.
micksam7 Bingo. It’s brutal on a normal 110v circuit with any other load on it. It does proper zero-voltage AC chopping (watch Louis’s teardown; they get the scope on it. It switches just like the Hakko or any other high end unit, it’s just much higher current) and basically everything else right, but there’s only so much it can do with weak sauce US mains circuits.
I came here to see the 858d in action because I just bought one and wanted to know how it would stack up against a professional machine. Thanks for the video. It really helped and I think I can do my amateur stuff with the 858d just fine. I just need to be a bit more patient. Great stuff!
Dave, shouldn't that stand be used the other way around? Both for the attachment removal (so the attachment falls into the cup below) and for the weight of the cable pulling the hot air iron into the stand instead of pulling it off of it like in the video at 4:50. 🧐
You can now get an 858d for 35$
Ditto. Works pretty well for hobbiest level. Been a great addition to my workbench.
Chryseus Do you happen to have a link to the CFW? Thanks!
I also have this Quick Station. There is nothing in this price range that can compare. Hakko and Weller is almost 3 times the price of the quick. I have mine for almost half an year and I'm still very impressed. Unfortunately mine has a "beeping" noisy motor with high frequency sound -.- but beside of that if you searching a hot air station right now. There is no way around the quick
I second this - Quick appears to be a truly high-quality manufacturer. My 861DW, btw, doesn't make any beeping or otherwise annoying noises.
@23:00 You need some Ceramic Tweezers dude. Nice device. As a hobbyist I'll keep on with my UYUE 8586 but if it stops working the Quick will be on the wish list. Nice video.
Louis Rossman is the man! 😍
no he is the Ross-man! :D Im gonna jump of a bridge now...
AcolyteArathok you deserve one internet
uuuh dont know if i want that xD with all the offended people and stuff around xD But thank you anyway! :)
@ruuhkis......"Rossmann"
I bought a Quick 861DA about 8 weeks before Louis got his... i'd been deliberating on it for weeks. Glad I made the right choice. Wholly justified by your review too Dave. Odd thing is I get the same light flicker as Louis.. keep up the good work :)
On the wish list for sure.
Nice fair review Dave. Stand was being used backwards, recessed bin area will catch tip when removed hot.
Finally decided to get one of these, after having it at work for a year. It's a great station and very nice to work with.
I had to laugh at the "LEAD FREE" stencil.
Can you see this thing overshoot glowing red hot at about 26:13 in the reflection of the pcb? That would be at least 650°C
9:43 Isnt that sleeving around the wires for heat protection?
This one's a forum classic, many many people have been recommending it for a long time.
It's funny watching dave do a similar job to Louis, but without adding 6 gallons of flux to the board before desoldering :)
I'd guess the flickering lights is from the heating element. When it's cold from being off or cooled down from being in the rest, it's going to surge the element at full power to bring the heat up as quick as possible, then likely PWM the power to the element to maintain heat. I see the same with my cheapo heat gun like the one you have. My entire bench is on an APC 1500va SmartUPS. When the heat gun 1st comes in it nearly maxes out the load the UPS can take for a few seconds, then it levels out to a much lower power draw depending on the temperature set
I always use the stand the other way round. That way the nozzles don't fly away but fall in the tray instead.
The 861DW is the 120l/min version! The 861DE can do 200l/min and has 1200 W
Louis will not know different settings he just put heat to max and regulates with distance. :)
tuxontour :-D
:)
Hello, you seem very knowledgeable of this product. I have this station as well and it's no longer heating properly. I replaced the heating element, and it did not fix it. It's barley heating at all. What is the most likely part that's causing it to not regulate the temp?
i just bought the Atten 858D+ for 27 euro.... price-performance unbeatable. for hobby stuff its great;)
wait what the heck
@3:25 - thats a shot from Louis towards Jessa from ipadrehab (who ordered these 45° nozzles first but Louis got them b4 her)
Questions, would the fact that it is higher temp inside of the Nozzle have anything todo with the loss of heat as the air travels to the component? I am looking at get a rework station. Never used one.
32:11, not You mistake, just use FLUX easy to remove after desolder process and vacuum tweezers to lift big BFA chips. Good to use termo sensor and best way to use preheater set to 100-150 st C. No to fast heat or internal silicon can crack.
If I understand correctly the 1meg ohm resistor from line to ground, supposedly for noise is something which was done to audio equipment in the 1960s-1970s. It creates a live chassis situation. I'd snip that out.
You have misunderstood the video. This is a high value inline resistor used to safely ground the earth strap socket at the back of the chassis. It isn't connected to the live supply in any way.
I got mine QUICK 861DW a few days ago. For my unpleasant surprise, the airflow controll on this brand new unit seemed to be stuck on max. level. If I went below 112, the fan just stopped and a few beeps later it showed "ERR" message on the display. Upon closer inspection of the motor driver board, I noticed that the R59 timing resistor is simply missing. Since my attempts to measure the value of the C53 were unsuccesfull, I just assumed it to be 10nF. According the MC33035DW datasheet, fig.1, with 10nF cap @ 25khz, the timing resistor should be around 4,7k. so I teporarily soldered one in between pins 8 and 10, and voila...no more error messages and the airflow controll appears to be working just fine too. But just in case, could someone please look at the original value of the R59 on the motor drive board and post it here?? thanks very much...
As for hacking it, I have replaced the firmware of a solder station with proper PID control as well as zero cross switchin on the triac. Also display of the real temperature vs. the set. Note that afaik the atten shows the real temperature only when it is in power down mode, when it thinks its up to temperature it never shows any overshoot, but when you then put it down, it suddenly does.
Regarding the loctite on the ground screw, I have seen some where this caused it to have no contact as it crawled in between.
The quick uses a remarkably well-tuned PID for temperature control. Dave's experimental methodology (sort of vaguely stuffing a thermocouple bead into the nozzle) is, well, poor. I set up a proper jig to hold the handpiece with the thermocouple in free air 5mm from the nozzle outlet so I could test/offset it properly shortly after I got it, and aside from the time taken to bring the nozzle up to temperature, the output is astonishingly accurate. Within ~5 degrees for the whole range, getting more accurate as the temperatures got hotter (up to the limit of my thermocouple anyway)
So when he says 'it must be lying about temperature, it can't be that stable' I believe he is mistaken.
Have you posted the Firmware?
Seriously Dave you're at one point suggesting that radiated EMI from a bench top device like this might cause the lights in a workshop to flicker?!?!? Too much coffee today?
I just picked this up as a side fun project to learn. I can't seem to desolder smd leds for some reason. Either I'm not getting it hot enough or I am afraid of torching stuff..lol this is my first time and I have mulitple PCB's that are dead and just practice on. I can't seem to get the hang of it yet. I know how to solder normally but totally new to hot air rework stations.
At 26:36 you can see the solder under the other D-PAK chip flowing, but not the one with the heat right on top of it.. Weird.
Louis even sent a 240v one!, Nice machine the quick, too bad it is impossible to find in my country
My brother in-law used to work at the Adelaide Showgrounds setting up and repairing power distribution points for show rides etc. They commonly referred to using two cable ties to secure flexible leads within an enclosure as 'Carnie Proofing'. Apparently the show-ride operators, or 'Carnies', had a reputation of being a little rougher than most with flexible power leads, often driving off with things still connected.
Two cable ties = 'Carnie Proof'
I was using a heat gun in my server room to test some temperature alarm points and noticed the lights flickering too, I think it's because these type of devices just modulate on/off instead of just adjusting the voltage to the element.
Compare Quick 861DW with Best BST-863, and with NT 762E, low price product to one category.
Quick 861 DW and Best BST863, inside the same, the parameters are the same, but the price is lower twice at BST 863. Do a comparative review.
Hall Effect type thing. I inherited mine without the stand so was unaware they auto switch off when in a stand. Drove me nuts while trying to replace the voice coil on a big woofer. Damn thing kept turning off when ever I brought it near the speaker. Had me stumped for awhile.
The Quick TS1200A Solder station is a perfect mate to this hot air station. It's a complete beast @ 120 Watts. I just posted a Quick / Hako comparison video on my channel.
13:28 the cable's copper seems to move inside the crimp. If those are not made correctly, can became quite loose.
Wait... Dave showed 200L/min for the quick - but all shops and sources i find advertise it as 120l/min just like the atten?!
Okay the Quick UI also shows 1-120 airflow... so nothing about 200 - so is the quick really better than the atten?
Yes, he was wrong about the 200. Is it better,? Ot depends on what you use it for. It does heat up faster with the 1000 Watt heater, has a better whirlpool 3 phase brushless motor and motor ESC controller board, proper mains filtering, program able to switch faster between ore-set modes (most hobbiest might not benefit from this, but can save time in production or repair shops) ground strap plug in the back if you don’t have a ESD mat (probably should still have one for professional work) and I think the Quick will last a longer longer for the money. Most I’ve seen sold are 2 year and 3 year warranty. But it mainly depends on what you really use it for, how often, all day at work or hardly used as a hobby.
Quick sell a 200L/minute model (QUICK856AE) with a larger motor/blower combination and a 1200W head. I believe some confusion is taking place.
Gadget Review Videos Ok, overall the quick sounds higher quality - what I am still confused about: if both have the same airflow: how can the atten perform so much worse (slower desoldering time) - I mean the temp is regulated so more power does not give you an advantage if you have the same airflow?
The Atten is lying about output volume. And probably temperature. The quick is not. Simple as that really.
It's hard for me to believe any of these tell the truth. My WHA900 feels like it has the same max airflow as the 861DW and it was rated to 50L/minute.
Anything that advertises over 25L/minute should be good.
It's the crappy hot air "pencils" built into 3-in-1 stations that are usually garbage, limited to 5-15 L/minute. Unable to do anything worthwhile with those and they often cost as much as a dedicated station.
33:22 Send it to Louis for repair! He 'loves' replacing BGA-s!
Fix my balls!
1:23 top right hand corner in the pop-up “screwing machine” lol
I got the Quick 857DW, so far it's been great.
Funny how a review of an expensive hot air station actually shows that the cheap Atten is more than adequate for my needs. Added that one to my wishlist. 🙂
It's even funnier you can't tell the difference. There's a reason it's a big seller.
@@bobweiram6321 Funny how you assume I can't tell the difference with absolutely nothing to back up that assumption. If your soldering is as bad as your reading, you'd better stay away from electronics completely.
Good review, would be interesting to see a review on one of Quick's 90W soldering stations.
When it gets hot those nozzles have a tendency to fall out
I ended up drilling a small hole in the collar and tapping it to put a small screw to retain the nozzle
initially comprehended the title as being a "quick review" at 37 minutes, it makes far more sense now that i see the name of the thing is "quick"
Love Louis Rossmann’s videos
Dave Approves !
That's why I bought one myself.
I'm a behringer at air soldering. Can I get some recommend tutorial videos for assembling PCBs (not rework)?
I'm mostly doing 0805 and 0603. Pcb heater plate essential, how to spread solder paste etc?
QUICK 861DW professional mobile phone repair and repair station, using brushless vortex fan, adjustable air volume, wide range, can be used for a variety of purposes.
The system has the function of automatic cooling of air volume, which prolongs the life of heating elements and protects the hot air handle.
I've read in reviews that some of these 858D units are dangerously wired. Are the gun shaped, paint stripper type guns worth considering for someone on a budget? Or completely unsuitable?
I think the flickering lights is the heating element cycling. No Zero crossing switch.
Have you seen that new atten station Louis is promoting (instead of the quick he used to sell)? Could you open one up and do a review?
I've got an identical unit as the Atten but called Hiyko. It doesn't display the overshoot of Dave's Atten and doesn't give me problems with the sleep detection. Could just be smoothing the temp value more or maybe improved control firmware?
honestly that temp memory feature on the quick is useful. I have an older cheaper model and switching between desoldering temps and lower temps for just melting stuff or shrink is a pain, many of times have I grabbed mine without thinking just to hit some heat shrink and its set at 400C
All reviews said cheap blower not so good and only for ocasional work, but thats what i needed so i bought it for 50 dolars. Impressive, especially for the price. Now your review is first where i see how capable cheap one is. True its slower, but with so much headroom on the temp i dont bother i will be needing more expensive any time if ever.
And one if best parts with my cheap station is it stacks perfectly with my other tools!
I've used Aoyue 968 for the last 11 years. Had to replace the soldering iron part of the station, but as for that, it's been a trooper. My only complaint is there is some radio noise around 150Mhz and again at 155Mhz that interferes with my testing of radios. I usually have to program the radios to something else so it doesn't get interference.
Here's my thinking.... You set the minimum temperature needed for the desolder and then adjust the power/speed with airflow, since the the heating power carried by the airstream is depended on temperature and airflow on equal proportion.
19:25 maybe the temp needs to be or can be calibrated
the collab I was waiting for...
