What is the difference between GND-sldr and GND-comp, Vcc-sldr and Vcc-comp? Could, or should, I just use GND and Vcc layers?
I ned to create a hole in the 1206 and 0603 footprints for reverse mounted LEDs. Would I pin statement in the element definition?
GND-sldr is primarily used for ground plane connections on the solder side of the PCB (a.k.a. bottom). GND-comp is for the component
side of the PCB (a.k.a. top). Vcc-sldr is for primarily for Vcc planes on the top, Vcc-comp is for the bottom.
Placing the planes (large polygons) on separate logical layers can make it easier see signal lines that are on the same physical layer.
I would place the hole in the footprint. I usually place a silkscreen circle around holes which makes it easier to see
on a black background screen.
