How long are the OSP boards out of there packaging? Is this a double sided smd process or single? Are the boards stored in nitrogen? Sounds like an osp issue to me!

I would be very interested in informations on OSP (organic solderability protection) on PCB�s. Good or bad experience with solderability, storage etc. There must be different types / brands of OSP. What type should be prefered ? And if possible

Thanks a lot Dave. I think I will stay away from OSP. I just thought that it could be a cheaper solution than NiAU for fine pitch. And I don�t trust the silver coating types. Brian

OK...I'm hooked on this subject. Were changing from NiAu to OSP as a "savings" and not because we choose too. So far we have had great success with BGA and are working on TSOP, SOP, etc. The only thing we have come to dislike so far is the ring aroun

Since you brought it up, Dave, I did check your math. Looks good to me! :-)

Over time, copper in the via will form an oxide with oxygen in the air.

Hello We introduced OSP finish on some of our products but now need to add some discretes at the end of the process. From my little knowledge of OSP, this is difficult. We'll SMT the boards and transfer them to another site for further processing.

Let me see if I got this right. The OSP in un-plugged vias will break down after subsequent reflows and washes which can result in oxidation. Question: Is there any paper covering oxidation and reliability on such a condition. We are averaging .0007

Question: Is there any paper covering oxidation and reliability on such a condition? Answer: Dunno, what does the 'sales-type' that talked you into this say?
