Just as important as peak temp is time above solidus (180 C). This
should be absolutely less than 90 sec, but try for about 30 sec. Less
is better.

Does anyone have experience soldering gold-plated SMT components to
gold-plated PCB's using a eutectic (Sn63/Pb37) solder? The solder
joints exhibit a dull, grainy appearance. Although I know that longer
liquidus dwell times and a maximum reflow temperature of 220 C are
typically recommended when soldering to gold, will other solder
alloys perform better (i.e,, Indium alloys)?
Thanks in advance,
