I would recommend using DSTF foils and not scrubbing, but rather using a
chem clean system to remove the chromate conversion and any other
contaminates present.  Scrubbing introduces problems in thinner
dielectrics and you resulting post lamination true position will be
unique panel to panel.

Sensitivity: Private

Trying to find out the proper way to clean printed wiring boards prior
to
imaging.

Should the board go through sulfuric bath rinse with DI water before
scrubbing?

Also the fact should I be using DI water at all in this stage of the
process?
