Peter,  The IPC-7721 has the procedure for pad removal and replacement.
Excellent instructions.
The pads and traces can be purchesed from Circuit Technology, Haverhill, MA.

Hope this helps.

Linda

Subject: [TN] Repair/Mod pads


Anyone know a source for 0603 and 0805 "Stick-on" component pads? A number
of our development boards require mods (don't they always), which often
involves adding extra passive components that weren't anticipated during
the original board routing. Rather than have loads of epoxy bonding down
the extra parts, I want to try using proper pads that I can solder to. I
know they're out there somewhere.

Supplementary question: these pads are usually fitted to a board using a
bonding press or bonding iron. Can anyone clue me in on techniques for
using these things to fit said pads? Or can they be fitted with less
specialised tools, normally found in an assembly shop?

Terribly grateful as ever for a share of the group know-how.

Peter
