Christopher,

A thickness of 3.5 mils seems a little high but in my experience 2.5 mils would not be out of the question.

Hello All,

Is there any specification regarding the max thickness of HASL plated
PCB's. We have recently received a lot of boards where the HASL plating on
the fine pitch device exceeds 3.5 mils. He have an extensive amount of
bridging on these devices now. Any help would be greatly appreciated.

Thanks
