Abstract
In an apparatus and method for effecting automatic handling of circuit boards prior to exposing them, pins are provided that effect highly accurate location of the circuit board at an exposure station. The pins are extended through slots provided in the circuit board, at least one slot being perpendicular to the others. Each pin is noncircular, being sufficiently small to be inserted through an associated slot when the pin is in one rotated position, but being sufficiently large that rotation of the pin about its axis will cause it to bind with the walls of the slot, so that further pin rotation is prevented. The pins are inserted into the slots when in the non-binding rotated positions, following which the pins are rotated so as to bind with the slot walls, and thereby move the board to a precisely known position relative to the axes of the pins. Thereafter, exposure of the board is effected.
