Hi,
Does anyone have any good tips for desoldreing these SM caps without
damaging the pads?
I tried wicking each pad dry but the darned thing still took one of the
flimsy little pads off with it. Also would it be OK to replace a SM cap
with a similar value radial if I support the radial with a blob of silicon
sealer or something after soldering ?
Any help welcomed.


Well,

Here is an odd possibility. One brand of stereo I service has a mod
that require removing 16 SM caps from a PC board. (That's the entire
mod). In speaking with a friend who also services these, he suggested
grabbing the cap with a pair of needle nose pliers and rotating the cap
until the leads snap. This usually requires about 90 degrees of
rotation. Then it's easy to clean up the pads. The caps are 10uf/16V and
have a black plastic base.

I'D SUGGEST TRYING THIS NO A SCRAP BOARD FIRST, as some boards may not
have the foil attached as well as these.
