On the 28:44 solenoid pump desoldering iron. I just bought one of these because of the reasonable price. I found it worked perfectly, if you use the right technic. Put it squarely on the underside let it melt the solder, hit the button quickly remove the iron and then let go of the button.
At about 10:50, Sometimes it's helpful if you poke a hole in the desoldering braid with an awl or tiny jeweler screwdriver so that the tip of the component lead will fit right through the hole and the desoldering braid is completely surrounding the soldered connection. If you use a beveled tip on your soldering iron you can also push the component lead down and partway back out through the hole as you are desoldering it.
At around 6:30 I think the idea is the other way around: put the pump on the solder side and heat it from the component side. In that way you should get a great seal around the bottom of the board while supplying heat from the other side. Thanks for the video Richard!
Another technique is to use an air compressor with a triggered nozzle. Melt the solder and blow a blast of compressed air at the hole. Works well, but leaves a mess; probably not good for regular use, but reliably does the trick if you have a problematic component that you can't easily remove with other tools. Just be careful to check/remove the blown solder.
For the gold coloured spring solder sucker .... make a small notch in the end of the suction tip to just fit over the iron tip. That gives you a much better coverage over the hole and a lot more direct suction.
And use a much finer tip on the Iron itself? I have found that the "tips" from flux syringes can be modified to fit the end of the manual sucker. Because they have a hollow metal needle you can fit them over fine pins and heat the needle with the soldering iron, then manually suck. They do clog up petty easily though so I find it best to remove as much solder as possible before using the "needle modded" manual sucker. That said solder doesnt seem to stick good to the chrome needle so it can be prodded out quite easily. Its just time consuming.
A 10mm length of model glow engine fuel tube (silicone tube) over the end of your manual desolder pump nozzle helps sealing the pump sucking action to just the hole you are trying to desolder, improving the results immeasurably.
A bigger issue he has is not holding the nozzle perpendicular to the hole, or even close to the hole on many occasions. They need quick exchange between the iron to melt the solder and then the sucker to remove it - and a hot iron too. I have silicone tube on mine - it helps a lot, and saves the nozzle too - though I do fit it holds lumps of solder and drops them all over the place if one isn't careful. I had to stop watching after about 15 minutes, as he seems to be deliberately failing, and I couldn't watch further...
@@will_doherty I'm not deliberately failing, I clearly never developed the correct technique with the manual solder suckers. I put this down to learning to use them (or not, it seems) back in the 70s and 80s when there was no way to learn this stuff apart from books and magazines and no one else at school then 6th form college was interested in this stuff. By the time things like the internet came along I had already long since moved to using vacuum desoldering stations and braid which is what we used at the repair companies I worked for. I was also using hot air guns to aid desoldering though those were the 'paint stripper' kind, like a big powerful hairdryer really. But that's how it was back in the day, if you are old enough you will remember. You guys know I have a real dislike for those solder suckers, but I will freely accept it is a (lack of) technique thing if that is the case.
Everything works well on easy to desolder boards. Motherboards tend to be very difficult with those tiny pads that don't conduct much heat and are often surrounded by large planes that suck up the heat. Basically, Mobos are MoFos when it comes to desoldering. :) No matter what technique, hot air assistance is your friend on such boards.
Which is why I chose the motherboard as the test case. No point learning the easy stuff, if you learn to do this on multilayer boards then anything will be child's play
it's painful to see people struggle when working...this is a great video showing wasted money, wasted time, further damage , all things that can be avoided by new comers to the trade/hobby...thanks for your hard work
Calm in worktime and temperature is essential to desolder parts. The desolder tools are one of the part to do the work but the workers skills are more important. Good Video 👌🖖👌. Live long and prosper.
@Mr Guru But a lot of RUclipsr received some equipement from manufacturers or decide to purchase it to help and inform viewers. It was just a suggestion, in case he didn't know this device, and wanted to acquire it. Peace man!
For the solenoid pump desoldering iron i noticed the nozzle tip used was too big for the hole he was trying to desolder. It worked after the hot air as the solder is properly melted. If the tip was smaller and fitted the hole properly might have worked better due to continuous contact with the solder.
It would be interesting to see the same de-soldering test but while using a proper solder with low melting point (aka Lowmelt solder). The biggest "problem" here was that there were large planes which sucked up the heat away. But also you have to think of this as the "worst case scenario" as others have pointed out mentioning that this is a multi-layer motherboard and not a thin single-layer one.
Great topic, as anyone that has done electronic repair work and has had to remove and replace a through hole component will tell you, this is one of the most challenging aspects of the job, second only to troubleshooting. While in theory it should be relatively easy, the solder and component leads often get stuck in the through holes and become hard to remove without damaging the delicate foil traces of the printed circuit board. I thought a desoldering iron would make this task a lot easier, until I actually tried one, and like some of the desoldering irons in this video, it didn’t do the job. One thing I don’t recommend is heating the leads and grabbing the component and trying to forcefully pull it out. Aside from the component heating up and burning your fingers, the lead will often remain soldered to some part of the through hole and you’ll wind up pulling up the copper foil circuit trace along with the component. A better idea would be to put the circuit board in a holder, component side down, heat up both leads by quickly by moving the iron between them, and let gravity gently remove the component from the board. However, if the component leads are bent, as they often are to hold the component in place when it ‘s initially assembled, this will not work. Generally, the larger the diameter of the component lead, the harder it will be to remove because the larger surface area will dissipate the heat from the soldering iron better, and there will be a larger surface area making contact with the sides of the through hole. For larger components, I recommend cutting the leads as close to the component body as possible, and then placing the circuit board in a vise, component side up, heating the leads, and again, letting gravity gently remove what remains of the leads. If the ends of the component leads are bent down and soldered unto the through copper trace on the trace side of the board, you may have to heat up this side of the lead as well. You also may be tempted to heat up the bent lead and try to pry it up straight from the through hole trace, but you must be extremely careful when you do this, as you’ll often wind up prying up the circuit trace along with the lead, potentially ruining the circuit board. If you’re successful removing the leads using one of these methods, you may still have some stubborn solder stuck in the through hole. I have found that using some flux along with a braid or desoldering pump is often the best way of clearing the hole. I have also tried using metal picks, heating them with a soldering iron while trying to insert them into the hole, but the diameter of these picks widens beyond the tip often making it impossible to insert all the way through the hole and these picks usually aren’t the best heat conductors. Which is why I’m extremely disappointed that he didn’t try to use those desoldering needles he mentioned earlier in the video that appeared to be the same narrow diameter their entire length. Ideally, someone would make needles like this, in the diameters of common through hole sizes, that could be inserted into the soldering iron in place of the soldering tip. The rods should be extremely heat conductive, but made of a material that solder won’t stick to, maybe like Teflon. On second thought, Teflon wouldn’t be a good material for this application because its melting point is too low, around 620-642F, but possibly a Teflon alloy would work. It also, would probably not be a good idea to insert the rods into the soldering iron in place of the tip, because you would then, have to turn the iron off with the rod inserted into the through hole to allow the solder to cool to solid form in order to ensure that any remaining solder can’t block the hole, and that would take more time. Better yet, I just watched a video in which they soaked a soldering braid in a petri like dish of liquid flux and then placed it on the through hole and heated it with a soldering iron. This method drastically improved the soldering braids ability to absorb and suck up the solder, so this is a technique you’ll definitely want to try.
The desoldering iron sucker,You will need to apply or add fresh solder lead first so that the old solder on the whole will change it's consistency,It will be less creamier,Then it will be easy to suck
I think all of these would work well on single layer pcbs . But with multilayer boards most do not have the power to melt the solder even worse with a big ground plane . i used to have a weller desoldering station but the spares got so expensive that i now have one simulare to yours that works well . I still think i can unsoler say a 70 pin inline chip quicker with brade. I have a friend who swears by hollow needles for componenets who,s legs are small enough for the needles to fit over..
Normal desoldering method from my younger days till today is a soldering iron + toothpick. Its cant be simpler than just stick a toothpick into a hole to displace solder. Yes, there excess solder left, but the hole is clear now. That solder-sucker is good when desoldering ICs with many pins, not for any other component.
Heya, oh a follow up from the other video. I thiink you made your point in this video that even with the component still in the hole it still doesn't work well
I found them cheap heated solder suckers are rubbish, I think if you were in desperate times desperate measures a good idea to actually get some use out of it would be to flux up the pins and use low melt solder to tin the legs then use the heated solder sucker. Not practical to always use low melt solder but it depends how much you're struggling. I am glad i'm not the only one who struggles with de-soldering components. I get to the same stage whereby i can suck up the top layer of solder but there is still none molten solder still remaining in the hole itself.
I believe you are slightly mistaken, as I explained at the start of this video I made a recent video using these tools (plus desoldering needles) to clear the holes from a motherboard after I had manually removed the capacitors. In the many comments to that video ruclips.net/video/EoLa9ebjwGU/видео.html a number of viewers said it was an unfair comparison as at least two of these tools are designed for desoldering with the component in place, and use the component leg itself to transfer the heat through to the other side of the PCB allowing the component to be desoldered. Using them to clear the holes afterwards is an incorrect use, they said. Personally I usually find it easier to desolder and remove the component first, then clean the holes. But that does not mean I am right and others are wrong, so in this video I used the same tools, apart from desoldering needles which are not appropriate for this method, too desolder the component in place and test whether those viewers were correct in their comments. The results were, well, interesting.
The failed ones work better on a single layer board i've tried the same desoldering pump that you've shown here and it did the job but imo a desoldering gun is the way to go for desoldering through hole components especially those chips with multiple legs, i wish you could've tested the desoldering gun on those large inductor legs they were just right next to those capacitors lol because i know that the other tools will fail
Well I could make another video about unsoldering the throughole inductors, I know the method I use and it could be fun to try some others. Fortunately those inductors hardly ever fail (like I never saw a faulty one apart from physically broken ones) and there are far easier methods to find a faulty phase in a VRM than removing the inductor
Thank you very much that will be a great video to watch for sure and yes you're right those coils are fail proof the only ones that failed on me are the axial inductors
Hey bud, been watching your channel for some time now and u r damn good at the repairs, but, was wondering if u r using any kind of component cataloging system to see if u have parts u need in your inventory?

On top of preheating you may even have to desolder and resolder with low melt solder a couple of times to succeed. It takes trial and experience to do the job not damaging the PCB ...
@ 7:11... Surely that didn't work;... because U didn't clean;... wipe soldering iron tip prior 2 using the pump after applying fresh solder... When U placed the tip;... 1 could C solder being squeezed out;... asking a lot 4 the pump 2 suck up...
every time you run into the same problem - not enough heat. if you want to work cleanly with large thermal masses use preheater, ideally - work ON ir preheater, other than that you can put stronger elements on those tools but modifying pump is complete waste of time as it wont change anything other than increasing chance of stripping pads
That is exactly my thoughts and what I was trying to demonstrate. The part about modifiy the manual desoldering gun by fitting a pump is in response to a comment on the previous desoldering video where someone mentioned there was a cheap mod somewhere on RUclips that made the €5 tool perform as well as a €200 vacuum desoldering station. I disputed that as I thought it didn't have enough power to melt the solder in the first place, and it feel I proved the point rather well.
I appreciate your videos otherwise I wouldn't be here. I just want to say. your method of removing electroclytic or any capacitor is not optimal! Yes, you can melt one end, yank on it then melt the other end. Every time you tug on a device, you're stressing the PCB traces. I suction-based desoldering iron would make much more sense, set at the correct heat. You melt the solder, suck it up and pull the iron away. A simple process. If it happens to, "stick" a bit, you simply break it loose with a probe of some sort, like a screwdriver. It will, "click" when the the joint breaks and you're good to go.
chinese descriptions are crap :D These needles are meant to use it with a desoldering tool to clean the nozzles of them and not to clean the holes of a pcb.
If you look around youtube you will find some videos showing how they do it. I saw one that was in english with french accent, he heats the joint then inserts the needle around the leg of the component and since the needle is stainless steel the solder won’t stick. Then removes the needle and the leg is free, you can do the same with the second leg (and he does it in the video) but at this point you don’t even need the needle if it is a two legged component. Hope this helps!

chinese descriptions are crap :D These needles are meant to use it with a desoldering tool to clean the nozzles of them and not to clean the holes of a pcb.
If you look around youtube you will find some videos showing how they do it. I saw one that was in english with french accent, he heats the joint then inserts the needle around the leg of the component and since the needle is stainless steel the solder won’t stick. Then removes the needle and the leg is free, you can do the same with the second leg (and he does it in the video) but at this point you don’t even need the needle if it is a two legged component. Hope this helps!
