Desoldering

 

I am looking for suggestions on how to desolder and remove a leaded capacitor I soldered in the wrong place on the SoftRock 40. One suggestion a friend of mine gave me was to use plenty of solder and plenty of rosin. I had tried to remove it using my digital controlled iron set at 650 degrees F, but I couldn't get the solder to melt properly on the component side of the board. He said that was because I didn't have enough heat conduction to the other side because I didn't have enough solder in the hole to do that. And also I needed to set the iron to a higher temperature, like 700 or 800 degrees. (I was trying to use some 1/8 " solder wick to draw it out, but wasn't very successful.)

Does anyone know the maximum temperature that can be applied to a plated through hole in this PC board? I don't want to damage the plated through hole.

Hi Bill,

Just cut the capacitor off the board and I will send you a free replacement. I use a stainless steel needle I got out my wife's sewing stuff to clear plated through holes as I apply heat with the soldering iron.

Thanks, Tony

I hadn't though of that. That would be a lot easier. It's a small blue leaded cap labeled 104K X7R100. It looks like 0.1 inch lead spacing.

Thanks a bunch!

I would simply cut it off, and remove the leads one at a time. Melting the solder and tapping it on a hard surface should work, or you can use desolder braid.
