Abstract
Routing a circuit board from the bottom side allows board removal from areas not generally accessible from the top side, such as board areas which are overhung by 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.
Claims4
In an apparatus for cutting a circuit board with a router, said circuit board having component mounted on and protruding from at least a first side thereof, the improvement comprising:
- means for restraining said board with said first side spaced from interferring surfaces by an amount at least equal to protrusion of a tallest one of said components from said first side in order to maintain said board in a plane generally perpendicular to a router plunge axis and to provide for routing through said board from a second side opposite of said board from said first side and so as to remove by routing circuit board portions which are overhung by portions of said components on said first side and thus generally inaccessable to a router from said first side.
