Here's a sneaky trick for stripping parts from
boards (to be used only with adult supervision!):


Cover a suitable area of your benchtop with a
sheet of wood (or whatever) to protect it. Wear
safety goggles. Heat up each solder joint until
it's molten, then SLAP the board onto the
protected benchtop. The solder will be ejected
from the joint and make a little splash spot.

After you've done this to each joint on the
component, use needle-nose pliers to wiggle each
lead from side to side (in case there is some
residual solder holding it to the side of the
hole), then pull the part.

This goes pretty quickly when you are removing
lots of parts from scrap boards. I amassed a nice
collection of expensive and/or hard-to-find (back
then) parts from scrap electronic fuel injection
boards when I was a whippersnapper working for GM
back in the early '70s. Stripped them over my
lunch break, on days when no other guys were in
the room to be annoyed by the loud noise!

Use a heat gun or propane torch, and remove lots of parts
simultaneously.

Solder wick for surface mount, but I love my solder sucker for
clearing through holes. It's an OK DP-100. I clean it regularly and
put some vacuum grease on the o-ring. Don't know the price, but I
wouldn't want a cheap one.

I put my finger over the hole. and 'click' the plunger. It should
stay in place.. if it rises up then I clean it.
