I typically cut the legs first and then desolder each leg individually. Just make sure you have a small set of wire cutters with really sharp edges (narrow point as well). Granted, my method ruins the chip....but it does save the board (no lifted traces...only worried about one hole at a time...etc.) jeff ----- Original Message ----- From: "Sean McLachlan" <sean@lithoflexo.com> To: <utvgg@mailman.xmission.com> Sent: Friday, August 27, 2004 2:39 PM Subject: RE: [UtVgG] BZ Repair.
- be careful with the blade end -- a lot of sockets have holes in them that will let you scrape the board traces underneath -- those are fun to find
Amen. I put 2 layers of electrical tape over the blade after I get the
chip
up a bit.
And a similar question I have: What is the best way to remove chips that are soldered to the board? Getting all 12 or 16 legs completely free of solder is almost impossible (can't get to the back of the legs). Is there a tip for a soldering iron that will heat all the legs on a side at once? It took me a solid hour to remove 2 chips, and it left the chips unusable. The chips were bad, but I'd hate to wreck a good chip pulling it out to test it.
