Lou:
What solder mask are they having adhesion problems with and what is
the surface that they are proposing to put the oxide on?

Greetings !
The Fab house that we use has recently asked us if they could use a black
oxide treatment on external layers of our designs. I know that this process
is used for internal layers but I want to know if any of you have used it
for external layers ? Their reason for using it is " To create better
adhesion for the solder mask and eliminate potential slivers ". To me, this
sounds more like a process problem. What do you think ?
To recap, do any of you use a black oxide coating on outer layers ? If so,
why ?. If not, why not ?
Thanks in advance for your help !
