I took a pad that did not have any solder flow (wetting issue with pad) and not reworkable with soldering iron, and scraped with an exacto knife. After scraping the pad soldered fine. Any suggestions?

Craig, If it is LF Hasl it sounds like it applied too thin exposing the intermetallic layer wich is not solderable. We call out a minimum thickness of 80 microinches and have good results. We have had shops in the past that did not control the Hasl

Boards with the LF hasl finish applied too thin will genrally pass the IPC test. That is some pretty agressive flux they call out. The boards usually wave solder just fine as well. Reflow is where the you see the problem.
