Re: Tempest

I've used countless methods to pull chips from boards (high end vacuum irons, molten solder fountain under the pcb, heat guns and snip-n-pick just to name a few) but the best I've found works great on double-sided PCBs and doesn't destroy the chip.

Get a nice controlled temp station (I use my old Metcal but that's serious overkill) and a tube style solder sucker. Heat up a leg from the component side and place the nozzle over the pin and hit the button on the sucker. It can be difficult to balance everything but the results are worth it. I've pulled 6821s from WMS sound boards in under 15 minutes without damaging the PCB or the chip.

> I know this is way old, but I'm just going to chime in and say that a soldering iron and solder sucker work fine and are a totally reasonable way to start. I've socketed a few chips on Asteroids PCBs, and it's been fine.

I use this method too - graduated from a straight vacuum solder sucker to a heated one (a bulb attached to a soldering iron) - Radio Shack still sells it, it's cheap, and it works fantastically well.
