OSP/immersion gold (I assume you are alluding to immersion gold) boards have 
been fabricated in Asia for several years for the cellular phone handset 
industry. The big issue I am aware of is in fabrication of the board; it has 
been necessary to use particular immersion gold processes, which your fab 
has is probably aware of.

Subject: [TN] OSP w selective gold


We have never used OSP for anything, but we may be required to switch
one of our products to it.  Can anyone point me in the direction of some
good solid info regarding working with this finish?
How common is it, especially if you need selective gold?  Are there any
solder process pitfalls to watch out for?
This is for leadfree products.

Thanks in advance,
Genny.
