Sorry I cannot help with this question but i am looking for more information on silver finish.

What board house is doing silver finish for you and what is the price difference from standard Tin/lead HASL.

Any information would be great!!

Thanks,
John

Hello Everyone,

I'm needing information on PCB's with silver finish. We are using HASL but having problems with our proto fab shop. They have a very hard time keeping the HASL somewhat smooth on the fine pitch parts. They sent us a board with silver finish and we ran it using our same process. Appeared to make a pretty good solder connection, just not as much solder on the pads now without the extra solder from the HASL. Are there special requirements on which paste I should use.. Will I have to use a thicker stencil... What is the shelf life before it tarnishes and can you solder if it is tarnished.
The information will be appreciated....

Thanks,
Danny
