Many fluxes used in board fabrication contain chlorides or bromides.

Subject: [TN] Chloride levels


Is there a standard for acceptable levels of chloride on assembled PCBs and
on bare boards?  What sources of chlorides exist in a board fabrication
process, and in an assembly process?

We are using a no-clean low-solid flux.

Thanks,
