I'm designing a 4-layer board using PADS PCB. Both inner layers are solid
ground planes. PADS wants me to select "CAM plane" as the inner layer type
and the gerbers are negatives. Is that customary?
The PCB fab wants "right reading when printed" text on every layer. What
does this mean?
I think it probably means:
Top Copper = Normal
Inner Layer 1 = Mirrored
Inner Layer 2 = Normal
Bottom Copper = Mirrored
When viewed from above looking down and through the stack.
TIA
