Hi all,

 

A question on the new RoHS gold plating for boards, is anyone flashing
the gold directly to the copper eliminating the nickel bath? I have read
that doing this makes the gold more brittle and it has problems with the
lead-free paste.  Also, is there anything new on the use of sliver
immersion, I read that the tarnishing of stockpiled boards before
assembly could be a good thing?

 

I know this is vague but the cost of PCB's has risen to 30% since we
have gone to ENIG boards and this makes it tough trying to be profitable
long term. ALL suggestions are welcome (come on you lurkers I need you).

 

Thanks in advance.
