13:14 use sandpaper and scratch the metal so the solder bond with the metal surface ... i always do this and it's very effective
Exactly! Apply some flux also. I always follow this for a successful soldering.
Me too, due to lack of tools (hot plate, powerful hot air etc...) 😊😅
sanding also effective on qfn chips pins
Nice repair Master! As always thank you for the tips and triks.
Aaaaaaaalso, FINALLY I STARTED MY REPAIR BUSINESS!!!!
without your lessons for the whole repair industry and repairs, i would not ever been able to start.
I got some hard jobs, i got some simple and pleasent jobs, and today i fixed an industrial Tractor machine the joystick connector and earned my First 100€ 🤩🤩🤩.
Thank you my Friend!
Congratulation dude 😁👍, just do good to your customers and I wish you success 👍
Quick tip: big soldering iron works all alone without hot air and pre heater. I worked on these kind of big things.
Yep, I worked on automotive/industrial stuff made like this ; 100 ~ 150w iron always
@@gcbification
My trick is to place the soldering iron in one place and put more solder and wait a few seconds untill all the solder get melted then i can do whatever i want 🤗
I think it could be done with a big iron, but could it be done without making a big mess ?
@@BrainHurricanes Yes, absolutely =)
I use a mico iron day to day and 380 is the 'not gonna do it' setting on anything other than small traces. A lot of jobs are set to 420 and the biggest tip. Something like this, the Big Gun comes out.
Good tip on using that Weller tip activator on a job like this. Never thought about using that. Thanks.
Avalon hashboard. Designed to dissipate +1000W of power and turn into heat. Best way to handle it would be high temperature torch. Yes it will still be hard to do with heatsinks removed (pcb is aluminum)
Time to buy a preheater Mr Sorin!
A Puhui T8280 is around 120 dollars.
You can also use an Infrared Cooker (it's better than a real PCB preheater sometimes).
Those T8280s go for well over $250 to $600 everywhere I look. (USA)
@@patrickauer6958 For T8280s, AliExpess is around £97 + £60 shipping + (uk has 20% vat tax).
Amazing job as always. For those who are wondering (as i was) this is an Avalon series hash board.
Great learning clip, and equally great suggestions in the comments.
Tipp: I used a soldier gun from Weller once for welding a wire to a metal frame. Needed a lot of energy. And also used special Flux for Zinc/Copper aso. for making the connection. Another time I had solder wire with acid flux embedded inside the solder wire. Worked great.
Device: Could be from a cryptocurrency miner rack.
Nice job! Always find a solution! That’s why I use Metcal soldering stations, they make all the difference in cases like this
yes like jbc, its because when you need more power it gives you that power thats why you pay more
@@sakis1991 100% agree. 250W JBC is really good to have on a job like this. I think Sorin said his Weller iron is 12V so it should be 40W one, not even 80W typical soldering iron. Crazy.
Greetings from Portugal 🇵🇹
I,ve loved the tips cleaner tip.
Thank you and keep going on learning because i'll keep going learning too👍
... And that is how a Master does the job with Perfection!
This one is very complicated soldering way! Happy Easter🙂
6:56 - Put metal item on vice, heat with brener, butane torch, maybe to the point where its getting red, then place it on the board?
13:45 - I have seen some videos people soldering with vaseline, it allows even to solder wire to aluminum plate.
22:35 - Not only this but sometimes they try to get away by putting pressure on repair man. Thats the moment when diplomacy starts.
When you heat metal with a torch, it oxidates and makes it impossible to take solder and bond to the contacts on the PCB.
@@oilybrakes I didnt explained fully, I didnt mean to treat it only with butane torch. Put a lot of soldering paste (kalaphonia, cinol) and to wrap around soldering tin, then to start heating, when its melted place board on top of item, wait to cool and remove item from vice.
Awesome Job, you are the Boss. Get well soon.
These ASIC hash boards are always a lil tricky especially if it’s your first time 💪 you did a good job
use a phone or tablet screen heat pad to bring up the heatsink assembly warmer. You used to use this ages ago
Great job. It's all about heat energy when there is a lot of thermal mass. Reaching that point where the job holds the heat long enough to solder. Temperature means nothing without the right amount of heat energy.
Project request: Ventilation Fan: Solder up 2-4 spare laptop fans to a USB connector. Install fans onto a cigar box that contains a cut to size carbon filter. Add vent holes in side opposite side. Better than USB power, show us how to wire the fans to your solder iron control. Make the fans automatically come on and off in sync with your iron. Use your hot glue to attach this on the far side of your desk!!! Or rig it up to your camera holder.
Sorin - I always enjoy your videos. If you have the flu you will have a fever. A cold, no.
Well done job 😊
A challenging job. There is a video from Mend It Mark (Kinki Vision THR-1) which, surprisingly to me, shows that kapton tape does nothing to prevent heat reaching other components, in one case it was being used as a thermal pad.
Very good job. You can make alkaline rosin yourself too. That sticks everywhere.. most people dont know this
I think you need a Handy Helper (weighted stand with crocodile clips on it) to help hold small items still, they're normally just a few quid but so handy!
I use the same technique on thick circuit boards, I have a small heat board that goes to 500 deg Fahrenheit or 250 deg Celsius, works great.
WE HAVE PICTURE!
Hope you feel better soon Sorin. Another great video 👍
Get well soon
You could use your phone heating matt to raise the ambient temp.
It's a BTC miner hashboard.
About 40 to 50 amps goes in the board.
Great video as always. Hope you feel better soon.
That part he soldered had two holes, i think it should have been designed to hold with small screw and bolt along with the soldering, in that case it would never come apart :)
Good job mate
Amazing job sorin a true repair master
Happy Easter to everyone ❤
It helps on things like this to prewarm the whole board in an oven to like 120f
Happy Easter🎉
I bought some Stainless Steel Flux Soldering Paste HWY-800 off ebay $3. It actually worked to secure a wire on shiny metal bracket that regular flux would not. Seems strong hold but didn't try picking up 5 pounds with it. The label of this HWY is in another language, composition unknown but it came thru customs and mail. It looks like water so guessing that it's just boric acid (borax & water mixed) which is common silver flux.
Sorin, having worked in assorted fumes, nothing major but regular I can tell you that all those damn "colds & flu" were warnings that I ignored. The lung irritants screw up protective lining of sinus and lungs, letting germs in. It heals but the scar tissue patches that look like brittle rosin flakes make lungs so they don't stretch when you get old. You'd be better off smoking regular cigs if you are going to huff rosin fumes. The sticky tar in the nose keeps the fumes & germs out of the lungs. Worse than emphysema, e-cig oil causes cotton lung very rapidly even in young people.
Avalon 1166 Pro hash board for BTC Mining.
That looks like an Asic miner board
Hi Sorin, thanks for the Tips & Tricks good Easter even to you and Family bye from FrancescoTimpano from Florence Italy
Get well soon Sorin happy easter
I remember people bring their tv into my shop and say it doesn't turn on when i push the power button i think it needs a new power switch it never was the power switch lol.
Sorin, that's why 250W JBC iron would be handy. Would be a lot easier. Although a little bit preheat would still be needed. Could get even away maybe without hot air. Poor tantalum caps.
Hi Sorin.You must use large tips so that the station can give the maximum yield. Minimum tips of 5mm
Peeerfect Sorin. God bless you!
Preheater is a must in any electronics lab
Happy Easter Sorin! Get well soon!
😊😊good job! Happy Easter!😊
He is romanian, so, most probably, is orthodox and Easter for orthodox people is in may. But, I have a feeling that Sorin is not a vary religios person 😀. Anyway Happy Easter!
i have a mini butane torch which i use for this kind of repairs.
I was just wondering if torches you use for soldering pipes would be usable here.
mot really, you will be having a very uncontrolled heat source. you might want to look into the mini torch which chefs are using for caramelizing top of the foods. those mini torches are a lot more manageable. @@CreativityNull
Absolutely brilliant!
Great job sir!!! 👏🏻👏🏻
Thanks Sorin, A140°C again ,Perfect Sorin! Happy Easter @ PCB My way Boards.?!
once I worked almost an hour to weld something used in the car, the guy said thank you, I told him he has to pay me, he replied: for this little weld I have to pay you? ...finally he gave me 5 euros even though I asked for 25 euros....people want everything for free
Always say your charges first & if the client is picky insist on paying in advance! Otherwise say no! That's what I always do!
Customer must not decide prices, you have to make it clear to them. If they want for free they should do it, or if they want it cheaper they must search for a cheaper place.
@@Aneesh.Asokanyes, I always tell them the price first and then proceed with the repair
@@maklogetrich2378 I don't have a shop as my clients reach me via reference! So I do have a general awareness about their background! Still if I feel a faint hint of hooliganism I may insist on advance payment! Sometimes I may refuse work if that person is not up to my expectations! I avoid verbal arguments as plague!😀
Get a 300W plumbers soldering iron for these kinds of jobs.
Get well soon Sorin , You the best ever @1000,10³ C° ³/1=COOL
hope you get better nice work as usual
it definately was a fuse issue on this one haha
Happy Easter to you Sorin !
An ignorant question from an ignorant enthusiast who enjoys Sorin's videos immensely. Wouldn't it help to remove the heat sink before soldering?
7:52 MiniWare MHP50-A5 preheater
You need a big fat tip.i kept my old hakko 88 with the fattest tips for stuff like this.
Never let anyone undervalue your work. People like us take pride in what we do and they are only doing it to save a buck,...not fair
Definitely need a preheater and a bigger soldering iron that tip is way way too small You're not getting enough heat out of it
I have an old large 100 watts solder iron that should be able to solder this ...
i use a solder pot for big solder jobs takes no time at all and cheap
Impressive
At what temperature does the board cracks? Like the fiberglass gets damage?
Won't it be better if you remove the heatsink first before solder it?
When soldering job customers moan about 25 quid, I tell them to buy a £20 iron in B&Q and see how they get on. I do quite a few DIY patch up jobs that would have been a lot cheaper had someone not ripped up every trace.
What's the difference between a hot plate and a clothes iron with the thermostat adjusted!?
Sure the flatiron is more powerful and cheaper...
Why didn't you remove the heatsinks?
How about removing the heatsink
i would have mixed it with low melt solder
Hello🤝happy Easter 🐣🐣🐣🐣
Happy Easter
you need a big iron
Isn't the acid gonna be a problem for the copper track ?
that is matherboard from Asic mashine for mining bitcoins
You just need a much larger soldering iron for this job, it would had melted the solder very quickly
tips for maintaining the tip, it keeps getting bad
SORIN, what time coffe tomorrow? I need to see live :)
this is harder for Sorin than replacing a EC chip 😆
Next time it may come with another hook holder .
Hello Sorin - Boss :)
you need a big solder iron like 150w old ones, not engineering career, you know , if not fit in, grab a bigger hummer...
gj, i scratch solder place and use acid, where i can buy this what u use?
Master Sorin: You need to try a cheap substance called Zinc Chloride. It is not an acid.
You thank me later :)
No preheater, no hot air, with one drop of Zinc Chloride and a cheap chinesium soldering iron, you can solder directly even thick steel items. In seconds.
2:37 not enough flux, you should empty the tube every time you use it :P
It's straight rosin not flux. It's highly acidic when heated. He didn't have enough heat and he obviously solved that.
@@B9NE *sigh* just have to ruin my dumb Louis Rossmann reference
@@CreativityNull oh I didn't even catch that I'm working on 5 psvr headset cables
@@B9NE lol it's no big deal. You got me to Google and learn a few new things today, so thank you.
@@CreativityNull no problem have a good day
If you would just stop moving the tip for a few seconds, you wouldn't need so much time and heat.
Damn GND
The correct tool for this job is Pistol 100 Watt Soldering Gun.
That's what Alex says..Better than factory.🎉
I would have screwed it through the pcb 😹
Why not just remove the heat sink?
Because there is so much termal pads that should be replaced, or termal paste to be replaced, or metal liquid starts moving around.
Definitively what I first thought
