We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have to bu

I have experience in this. My company offers Lead free SMT and Wave soldering. I have processed ImSn, ImAg, Enig, OSP in both smt and wave. Yes, silver leaching will occur. Yes, copper leaching will occur. High tin content solders disolve everyt

I have been using silver coated boards for over 3 years and with a Qualitek No-clean solder paste and have used primarily the same convection reflow profiles as Hasl boards.

As long as the surface is solderable, you should be fine. Silver tarnish a well0-known thing. Make sure, though, there is no sulfur (S) "around". Regards, Vlad

Grainy finish of the solder joint also caused by higher reflow temp.So far we have observed grainy structure in case of gold plated board.

I have heard that the profiles are pretty much the same but I have a visible solder joint difference... might half to start looking at the plating, might be something with that?
