2 ways i've used to get stuff off of circuit boards:<br>
<br>
the messy way: hold the board solder down over a gas stove until the
solder starts to melt. them smash board hard on the counter.. voila,
almost all parts will come flying out, including ic's resistors, etc.<br>
disadvantage: it stinks because a lot of times the board also starts to
melt. and the solder can get onto the counter, so it's messy. <br>
<br>
the better way: use a small gas burner and do it outside.. i have a
small thing, it's like a portable soldering gun running on gas, it's
fairly easy to get it to run the flame over all the soldered pins and
get the solder to flow on all pint, then flip board over and tap on
something. 99% of the time the ic comes out.<br>

It's pretty hard. If you want to be sure not to damage the PCB then you<br>are better off sacrificing the IC - cut the pins and desolder individually.<br><br>But you can get special soldering iron bit that will desolder up to a
<br>16pin DIP IC all in 1 go (it sits on all pins at once). This is the<br>best way I can think of. Maybe with a single sided board you'd be able<br>to manage by removing the solder with a solder sucker or desoldering<br>
braid, but with double sided PTH boards it'll be near enough impossible<br>to do this.<br><br>Seb<br><br><br>steve jones wrote:<br><br>>Newbie stuff.... I've always used chip sockets for my DIY projects so<br>>far, so this is new to me...
