Has anybody expierianced solderability issues on electroless nickel boards that do not have gold immersion? We recently tried to process boards of this type, and I may as well have been trying to reflow on plastic. Any ideas?

First, while black pad can be a problem with poorly controlled electroless gold [search SMTnet Archives for background], it is not a suffiecient reason to use electrolytic. It's the reason the supplier should fix their electroless gold process. Se

What's wrong with the Tin? Just wondering MDCox | | Electroless silver had promise, from Alpha, but I don't know where this ended up. Also Omikron's "white" electroless tin is proported to be a good alternative, though I've never been a big fan of

| Is there any problem using SMT on gold boards? 15 years ago we were told not to use gold boards, but I can't remember why. Judging by the other postings it now appears to be common. Only problem I see is that the nickel should be plated, not ele

My name is Geertjan de Beijer and I am new on this forum. I have a question about Electroless Nickel/Gold finishes. Until now we always use a HAL finish on our PCB's. Since we are using compontents with pitches of 0.5mm we notice that the HAL finis

Roni: Ron gives good advice on the thickness of your Electroless Nickel - Immersion Gold (ENIG) solderability preservative. Several additional comments are ENIG: � More expensive than OSPs and HASL. � Much flatter surface than HASL, similar to OSP
