Barrel bright acid copper process FFI-22
FFI-22 is a bright acid copper process formulated to produce a fine-grained, excellent coverness,
uniform, bright copper deposit. The process exhibits best capability of uniform plating. It is for
The capability of uniformplating is excellent, even plating through hole;
The deposit exhibits brightness and the excellent capability of uniform plating;
The deposit has no stress, and is suitable for thermal cycle test;
No need to treat the plating solution with active carbon for long time.
