                      ass: gold/Ni solder skips
Hi
I'm wave soldering a board with gold/nickel finish and I've recently seen
some bizarre incidents of certain pads entirely not wetting, some with a
slight degree of wetting and the majority showing very good wetting.
I have a gut feeling that it's related to variation of temperature in the
solder bath but I really am not sure why its recently started happening.

Any opinions welcome.
Thanks in advance.
