All:
One question about the Pad Discoloration Spec. (Immersion Gold pcs...)!!

I don't think the IPC has the Spec., right?
Is it required to use acid rising after the E/Test and FQC inspection???

You know, right now we just use the water rinse and 120mins baking
right after the Routing Process and then E/Test, FQC, OQC and Packing.

A lot of Pad Discoloration Quality Issue Feedback recent time!!!!

THKS.
