ABSTRACT:
Routing a circuit board from the bottom side allows router access to areas not generally accessible from the top side, such as board areas which are overhung by electrical connector "headers", as well as variable potentiometer and capacitor controls which may not be easily accessible from the top side. One embodiment combines such routing with shearing to merge their respective advantages.
