Sona,
Ionic contamination by what measure and what is the pass-fail limit?
Contamination is a subjective term. Depends on who you talk to.

Hi Fellow Technetters:
I would like to know if there is a process to clean inner layers for
ionic contamination. Generally we drill, laminate, expose,develop,
inspect, etch, blackoxide, bake and press inner layers. Its a multilayer
board we are building for military and requires no ionic contamination
between layers. (inner or outer).
Regards
Sona
