One thing they recommend is a metal former, basically a chunk of metal with a capsule sized hole drilled in it, with a smaller concentric hole that goes all the way through, to act as a heat sink.?
You put your capsule in the hole and only keep the soldering iron in contact with the solder pad for a second or so.?
I like to use leaded low temperature solder, but that doesn¡¯t work well with pre-tinned capsule pads.?
It does seem pretty crazy that the heating due to soldering would alter the response but I guess the diaphragms are extremely thin and delicate.

Forgive me if I'm highjacking a thread here (I did change the subject line), but isn't there an alternative to soldering these valuable and sensitive condenser capsules? Maybe slver clay or paste as used by jewelers?
If not, then can someone please direct me to a soldering protocol that includes materials and tools lists??
Or are there versions of these ideal capsules that have wire? leads??
I've got a nifty DIY project but I hesitate to jump in exactly for fear of capsule and PCB heat damage.
Thank you,
