4 Layer Construction
? Layer 1: Chassis Ground (component side), full coverage on component side;
also available on solder side, isolated from circuit ground.
? Layer 2: One or two auxiliary voltages (AUX ? A and AUX B) can be delivered
through Mate-N-Lock connectors; AUX A and AUX B (typically +12V and -12V)
accessible through gold-plated wrap power pick-ups - three each at most slot
positions.

? Layer 3: Source power is delivered through Mate-N-Lock connectors and/or
Power Bug connectors on solder side; +5V is accessible through gold-plated,
wire-wrap power pick-up pins - 12 pins available at each slot position.
? Layer 4: Circuit ground (solder side) can be dedicated to chassis ground using
pins and solder washers (supplied with backplanes); and is accessible at any pin
position and through Mate-N-Lock and Power Bug connectors.
? Full Power Planes - four independent power layers, one can be split between
AUX A and AUX B - low impedance power distribution.
