Subject: [TN] ionic contamination
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
