Re: Doing Layout on two outer layers in OrCAD



A straight mirror can be dangerous. Protel 99SE has a mirror and change
layer commands.

The Mirror is handy if you want to mount a chip upside down. Why you ask?
I once did a demo board for a remote control. All the SMD component were
mounted upside down with holes cut into the PCB so that the height
restrictions were met. I believe the final version was going to be
chip-on-board with thick film discrete.
