Vic,
The boards are HASL-SnPb. I am expecting the worse, that they were
stored in an uncontrolled environment.

Lee,
Yes, EDTA, BUT can you be sure you have got it all off of your board,
especially from the solder mask?

Subject: [TN] BOARD SOLDERABILITY
One of my colleagues has a HASL finished board, that sat in our
stockroom for ~ 10 years, and of course he want to use them (EOY
Billing).
Ran the board through wave soldering, and it did not solder at all. Good
news was that the board was not damaged by the heat - it just was not
solderable. I do not want to use a more active flux since it will be
difficult to clean.
Are there any solutions / processes that can restore board
solderability?
Thanks in advance.
