ABSTRACT:
This relates to an apparatus and method for marking printed circuit boards with numeric, alphabetic and/or symbolic indicia. Insertion of a printed circuit board causes a plurality of punches to come to rest on the board. Further insertion releases a striking hammer from its rest position permitting it to fall on the punches thus impressing the required markings on the board. The downward motion of the hammer causes a motor to be activated which returns the hammer to its rest position after which the motor will be turned off.
