Fellow TechNetters:

   What are the guideline for Forced Rework on PWB.   How many time can a PWB and/or components be reworks and yet have a reliable assembly.   I am taking into account the raw board thickness and if process for HASL, thermal excursion,.   My concern here is Td of the laminate.   I hear that 8 is the magic number.   What are the consensus out there.

Victor,
