Rey - the same group that worked on the ENIG specification is currently
working on both an Immersion Tin and Silver specifications. Following
publication of these we will begin work on an OSP specification, electroless
gold specification and finally anything that remains (HASL?)

Gerard,
Does this new IPC specification covers other finishes such as Immersion
Tin, Silver etc? I ask because we will be starting to produce this types of
PCBs.
Thanks.

Ervin - get yourself a copy of the new IPC4552 specification covering ENIG.
Use this document to specify the ENIG finish for your PWB's.

Hello Everyone,
I wish to present you with an issue that has troubled me for quite a
while.
We have been ordering more and more PCBs with ENIG finish and are
generally pleased - it's flat, it solders nicely and the products seem
to be O.K.
However, on the other hand - we are very well aware of problems
associated with ENIG, i.e - the "black pad" phenomena - solder joints
cracking, components actually "popping off" and other "goodies".
I am looking for good means to evaluate my ENIG finished boards,
before I waste a considerate amount of money while trying to assemble
them. Luckily for us, our manufacturer seems to understand our dilemma
and is very willing to cooperate with us on performing any in-process
or final test that we specify.
So, here's the catch: what do I specify ?
Assume that you could ask for anything (within reason, of course) -
what tests would you ask your manufacturer to perform to assure you
that he will give you high quality ENIG finish, good solderability,
durable, long life solder joints, etc.?
Thank you in advance,
Yehuda E. Weisz
