Here's a tip if you have one of those desoldering guns like Bil is showing at the beginning of the video: If you use it a lot and don't want to go out and buy new filters all the time, but a little wad of steel wool into the glass tube in front of the filter. It will catch the tin before it reaches the filter and the actual filter will last a lot longer. The tube fills up a little faster but replacing a tiny bit of steel wool is much cheaper than a filter, and probably a little more friendly to the environment too, because it may be possible to recycle steel and tin but not a filter.

on a difficult part such as a smd IC or something with a large ground land underneath the pad, a electric heat gun works in a pinch, but you have to be careful as you can cook the board. give it a go you will be surprised how well it works. but it can blow the parts around if the gun is on high.

What I really need is a good thorough video about using *and maintaining* a desoldering gun. It seems to me that I must be doing something terribly wrong based on the performance I get. The manual has been praised for being thorough and well-written, and I’ve read it cover to cover multiple times and followed the instructions to the letter wherever possible. One issue: The manual tells me to clean it after every use and gives me some silicon grease “for cleaning” but only tells me how to unclog it with a pin and drill piece... no instructions on what to apply the grease to so I put it on the cylinder, inside and outside of the spring filter, and O-ring seals. Perhaps I’m supposed to ram this gunk down the desoldering nozzle?! I unclog it constantly because it clogs constantly but even when it isn’t clogged it just doesn’t remove solder as well as it should. When it was brand new I got about ONE good use out of it before performance suffered terribly (removed an Atari 800XL cartridge connector to correct a mangled pin). It seems that I can only get about one or two good pulls between cleanings, which has led to a lot of damaged traces, stuck pins, and ruined projects/repairs. Even a freshly cleared tip that was used to clear one small component and still pulls solder will freeze up when I try to run the pin through it, requiring the drill. I have to do it every few pulls or else it just clogs... or worse (appears to empty the holes but doesn’t). One large DIP can take me an hour due to constant clogging and clearing. Either I’m doing *something* terribly wrong or this piece of junk just doesn’t pull strongly enough. The impressions of other people make me think it’s just me. I’m following all the advice I’m aware of including adding grease leaded solder to every connection (working on older non-RoHS electronics anyway). It’s an Aoyue Int701A++ from 2016 but it has the older, “more-robust” AC motor as opposed to the newer DC motor version. Even if my specific equipment is to blame, such a video would help anyone experiencing the same uncertainty as me with any similar equipment. It seems to be a big missing hole when I search for videos about these things. I’ve been using it semi-regularly for two years now and I’m at the end of my patience since my drill piece broke for a second time yesterday while in the middle of several huge projects so I can’t even brute force my way through like I have been. If I’ve been doing it wrong I really need to know. If I’ve been doing it right it would’ve been great to know while I still had a warranty. :(

The indicated reply to this old comment of mine appears to be ghosted. :( Anyway, it’s been many years since I made that comment and I have since figured out what the problems were with my Aoyue Int701A++ desoldering station. It was two-fold: First, the fume extractor function from the soldering station side causes flux particles to build up and restrict the point where the internal tubing connects to the filter housing (behind the cap with the barb for fitting for external tubing). You can’t see it but mine completely clogged within one year of occasional use. The worthless filter there was still perfectly clean. I had completely cleaned out the pump and replaced the handpiece before I found the constriction, but that doesn’t explain why I struggled so much prior to the clog developing. Well, it turns out that the weak pump just doesn’t spool up fast enough to clear a plated through-hole on a two-sided PCB. It ends up removing solder from one side which breaks the vacuum seal and the heat bridge that keeps solder molten on the other side. The molten solder on the other side always solidifies while I’m still pulling. Slow and weak is a bad combination that makes it only suitable for single-sided PCBs unless you know the trick. That Atari 800XL I did back in 2016 didn’t seem to have a ground pour or plated thru-holes, so I got lucky picking that as my first desoldering job. I bought it primarily to remove the two 40 pin DIPs (CPU and PPU) from dozens of Nintendo Entertainment System boards (Hi-Def NES installations) with plated thru holes but it proved worthless for those without the trick. About the only thing the desoldering part was useful for in the first 6 years owning it was removing capacitors on single sided PCB power supply boards, which I usually found easy enough to remove without bothering with the desoldering machine. Meanwhile, it proved worse than a soldering iron at removing thru-hole caps on most things I bought it for, like a TurboDuo/PC Engine. “The trick?” Glad you asked: While the solder is molten on both sides, kink or pinch hose, pull and hold trigger to build suction, then release/jerk hose straight to instantly pull vacuum from the nozzle at full strength. Obviously, this can get tedious for large DIPs and such so I’d like to rig up a trigger-controlled solenoid like Kainka Labs did. With the station’s fume extractor function I can already get the pump to stay on while I go down the line. Was fighting this station since 2016 and only figured that out in 2022 (currently 2023).

@theappreciationpost 8 років тому
great video. Would you say 350 celsius is on average a safe temp to heat without losing pads?
@emmettturner9452
@emmettturner9452 6 місяців тому
The only desolder jobs I’ve managed to do at 350°C are the ones on single-sided PCBs. The right temperature varies wildly because it’s not a cartridge-style tip with a built in heating element. The temperature monitoring is even more disconnected from the workpiece so the digital temperature controls can’t reliably maintain lower temperatures, especially with high thermal mass like a ground plane or beefy power trace. You have to make sure it flows both sides simultaneously and maintains that flow until the solder can be pulled from both sides, which means you really have to crank that temperature for plated thru holes.

Hi, very good tips but I have a big problem removing SMD and through holes DIP parts from boards that have conformal coating silicone applied to protect these boards against humidity. Do you know to remove this protection? Regards, Fernando Pompeo call sign PU2PLL Brazil

so the spectrum of light is harmless? thank you for answering by the way.
@JeffDM
@JeffDM 9 років тому
UV might be harmful, depending on the spectrum. Infrared is safe. It's the same as radiant heat.
@hackaday
@hackaday 9 років тому
bruce wayne Well the light is bright, so I wouldn't say it cant be harmful if you stared into it (which I had spots when I started the camera from looking directly at it without my sunglasses) but not due specifically to the longer red and near red wavelength. I did work for one of the early companies to try and use the iris pattern of the eye, or more specifically the blood vessels, and they used a near infrared wavelength. I believe they vetted the exposure.

IR is low frequency light (below red). It is UV (high frequency light above violet) that causes damage to cells. The higher the frequency the more energy.

@BilHerd
@BilHerd 9 років тому
Yeah plus I used bigger wick than normal, the one I wanted was probably under one of the mic standard or something. (shooting a video triples the amount of stuff in the way.) Scrub was probably a bad word on my part, I was using the motion to feel for bumps which is why I go lengthwise. Once I find a bump I try and apply the iron in a way to wick the bump away. I also would probably use more flux or a better flux impregnated wick if I was going to reuse. Jaroslav, do you have an alternative method for getting the pads flat enough for a new chip?
@SetMyLife
@SetMyLife 9 років тому
BilHerd Thanks for the response. I have worked on boards containing little VQFN packages. Quite a few of them failed. In the process of replacing them I discovered that physically moving the wick across the surface makes pads go bye bye. The method I now use is to simply put the wick on the pads and move the iron over it, while the wick stays put.
