 TNetters godday.

Target is very large metal packages with bright nickel finish. Imagine soldering hermetic feedtrues. Nickel needs higher temperature and longer exposure time than copper, silver, gold and other metals. Vapour phase soldering is maximum 218 Centigrades, which I believe is not high enough. Iron soldering is not practical for launches. IR oven could be an idea if we add protection gas. Hot gas stations (Nitrogen)seem to be too lame. Resistance soldering not tested, unknown for SMA. Torch heard of, ought to be impractical, will burn flux and miscolor package. Laser soldering not practised.

Anyone out there with experience from this kind of soldering?

Inge
