Yes, the parts (components, not boards) are made in Asia.

Just call me Bev.  Mr. Christian sounds too "Mutiny on the Bountish".  :)

Mr. Christian:

Suspect that the fabricator  may not be rinsing the parts well after
application of the juice.

They apply hot....if the parts dry between the application and the rinses,
and the rinses are cold....this could spell a problem.

I assume that you are using boards made in Asia?

:)
I am on the receiving end of this one, Rudy.  We do not make the parts, but
are receiving them and we are wondering if this material is why we are
having solderability problems, i.e. it is not "getting out of the way" of
the molten solder front as it wets across the lead.  When we take the parts
and sonicate them in IPA and then test them they do MUCH better.

Mr. Christian:

You called sir?

You called it exactly, this juice is an OSP type product.

When you have porous Gold plating on top of Nickle, any exposed Nickle sets
up a galvanic cell, and tends to oxidize/corrode more quickly than if it
were exposed without being in contact with Gold.  This stuff reacts with the
exposed Nickle, and renders it less reactive...it is actually a very elegant
idea, because it will only react with exposed Nickle (contrary to their
website) thus the possibility of there being ANY effect on conductivity is
virtually nil.

Now, is this really an issue?  Am I missing an opportunity?  I wouldn't want
my fellow Techneters to have to import this stuff from Japan...and I am
always ready to assist whenever I can..   I can already see the name....ONP
BC  "Organic Nickle Protection....as suggested by Bev Christian.
