Hi All,
I have a requirement with splitting the bottom soldermask into two secti=
ons. The bottom layer is a split ground plane with an area seeded with digi=
tal components and the remainder seeded with a number of signal related via=
s that are not grounded. The section containing digital components is to c=
overed with the usual mask covering everywhere except the pads. The second=
section is opposite, cover the via holes and expose all the copper plane. =
Hence a negative of the usual soldermask.
Does anyone know how to pull this off? I'm using PCB 20110918 on Fedora=
16.
Thanks in advanced, RM
