To Tony Bugeja

There is so much you haven't told us!  But...

GOLD:  Yes the gold can become the dross.  Very
messy-comtaminating the solder pot.  One must
contantly monitor the solder bath.

SILVER:  First of all why are you still using an RMA
flux? Isn't the industry leaning toward  NO CLEAN.
The tarnishing issue:  I would first monitor the temp
of the solder bath.  It may be too hot!   We have used
silver leaded headers and not seen a problem with
tarnishing.   The acid in the flux may be attacking the
silver.   We have seen tarnished leads from the field-due
to contamination.  Our fix was to encourage the customer
to coat the leads(posts) with  a Nyogel Lubricant.

Good luck
