Hi,
I want to use the big discussion that went on last week about black oxide etc. , to ask you all about a little different thing.

The discussion was about black/brown/red oxide and reduced surfaces.
What do you think about oxide substituents like the "AlphaPrep" (an organo-metallic compound of Alpha-Metals) or simmilar ?
Especially on FR-4 and polyimide innerlayers .

Could they lessen the problems long associated with the oxide treatment - such as wedge voiding and pink ring ? What problems do they have ?
