Solder for hand soldering

[Marcus Halberstram]

Also handy is the so called “acid brush”, which is available at most hardware stores. If the bristles are a bit too long, it is a simple matter to trim them with scissors.

I use two methods to make de-soldering fast and easy. (1) Make the thru holes BIG, where component legs are soldered. I use my own slightly customized PCB footprints when laying out boards, ensuring large diameter holes. This allows a desoldering pump sucker like Edsyn DS017 Soldapullt (link) to pull all the molten solder out of the hole, from both sides of the PCB at once. (2) Spend big money on a Hakko FR-301 electric vacuum pump desoldering gun, AND keep it scrupulously clean. Empty and clean the chamber often, to avoid "plugged up" misbehavior.

I ordered another Edsyn DS107 -- this time Amazon is not putting a picture of the device in the order acknowledgment for "privacy protection".

I suppose that it may have another purpose other than that for which it is intended.
