Thanks for the tip. I can't tell you how many pads I've lifted over the years. I now use a very small pointed tip and some steel wool on the opposite side of the hole. Your tip is a lot better, less chance of damage, and a whole lot easier. Going to do it your way from now on. TNX again.

Have a cert for mil-std soldering and have worked many mil-avionics boards. An actual better technique with less heating and repeat-heating is to use finely stranded silver plated wire (usually found on teflon and available if you look; esp. mil stuff). By first lightly tinning the very front of the stranded wire, (without excessive wicking) then trimming to leave just a small solid tip, you can then saturate the reset of the strands behind with a good grade f flux; make sure to leave the insulation on the help keep the strands stiff and aligned. Then, you place your tinned iron on the pad, then follow with the wire atop the hole and apply heat now to the wire. The outside will soften and allow you to push it through the hole before the center of the wire softens and gives way. Finally, shove the stranded wire in about 3/8" slowly then immediately pull back up. This may sound like a lot but yu will quickly get the hang of it and only subject the pad/hole to 1/3 the amount of heat and stress. The fluxed-stranded o(and silver-plated) wire is so-so much better at sucking up the solder...

Just melt solder with soldering iron, and put wooden tooth pick in hole. You cant make any damage with toothpick, yet you clear hole by pushing solder away.

I fought with my cheap desolder station from 2016-2022 before discovering the necessary trick for power and ground planes. Pinch the hose, hold the trigger, then jerk the hose open to get a stronger solder pull. When I don’t do that on power and ground planes the vacuum motor will spool up too slowly and will only remove solder from one side. That’s because the solder on the tip side comes out while the motor is still spooling up, breaking my air seal and heat bridge before suction builds enough to pull solder from the component side… which has consistently solidified a fraction of a second too soon. With the trick I get an instant full-strength pull when everything is still molten and sealed against the desolder tip. Someday I’ll rewire the trigger to a solenoid and abuse the station’s fume extractor function so that I don’t have to pinch anymore.

Thanks for this. I dont have anything to heat the board to 200*F, but did try using the lead of a resistor to push through, and on the way out used a wick to absorb what was there. It helped get me out of a jam I was in for several hours after my desolder station didn't want to suck out whatever was blocking it. Ground on a multi layer board like you said happens.

Try using a heat gun if you don't have a heater you can at least do one lead at a time

An interesting technique, I do something similar without all the pro gear, I will include solder wick next time. I think you have a very interesting channel about board repair, if I may, I'd like to suggest that you get some better camera equipment for close up videoing so we can see exactly what you are doing. Your description on this occasion was excellent but I fear when a repair that has a more complex procedure will not be as clear in spite of the excellent verbal description. Subbed.

helped me out of a jam replacing an hdmi on ps5. solder sucker would not work. i didn't use solder wick. i didn't have bus wire so i stripped a few strands of cat 6. used a wagner furno 750 heat gun since the 500 watt heatgun rework station was useless. pushed the cat 6 trough the hole, cut off the portion below that was covered with solder, and continued that process until the holes were clean enough to drop in the new hdmi port.

Wow. This is primitive. Any decent soldering workstation includes a vacuum powered solder sucker that makes this task a complete no-brainer. I got certified for avionics soldering in 1983 at Keesler AFB when I was a full time bench technician, and I can't believe this is even considered a good option when there are so many better tools to do this same thing with ZERO damage to the board or the runs. This is like using a mechanical wire stripper when a thermal stripper is head and shoulders better than any sharp cutting tool for stripping wires, especially when the insulation is Teflon as it is on all modern aircraft.

And that one country has the largest economy in the world, has put men on the moon, and still leads in the development and production of technology. Maybe *you* should get with the "program." Anyway, if you think the units of measurement commonly used in a country matters, then you're a fool. In reality, Americans use *both* traditional imperial *and* SI units. I use them interchangeably myself (I convert °F to °C in my head, for instance). You only use one system, and in your case you can't even spell the units properly. The words are _Fahrenheit_ (named after the _German_ who created the scale) and _Celsius_ .
