Hello,

I recently sent this message, but I have not received any reply.

Does anyone have experience with determining the acceptability of epoxy spots?

I understand that it depends on the PCB shop's pre-clean process, however,
it seems that more shops are narrowing their process windows with less
agressive chemicals (epoxy spot removal).  It seems to me that there needs
to be some formal acceptance criteria.

IPC Spec. 4101, Specifications for Base Materials for Rigid and Multilayer
Printed Boards, does not address epoxy spots.  Does anyone know of a
specification that addresses epoxy spot acceptability criteria?

Thank you for your answers,

Joel Fillion
