ABSTRACT:
There is disclosed a scoring cutter for scoring printed circuit boards to a uniform thickness. The scoring cutter has top and bottom circular blades set to a gap and rotatable in opposite directions to each other. Resilient wheels, four in number, having diameters slightly larger than the blades, are mounted for rotation with respect to the blades, one on each side of each blade. A circuit board is fed between the blades, and the resilient wheels position the circuit board in the gap between the blades.
