Abstract
Methods for qualifying the accuracy of a circuit board may include providing a printing mask pattern for first and second sides of the circuit board with a first sequence of spaced indicia parallel to a first edge of the printed circuit board, and a second sequence of spaced indicia parallel to a second edge of the printed circuit board opposite the first edge. A layer of visually conspicuous material may be printed on the board using the mask patterns. The board may be separated or cut to a predetermined size thereby removing, at least a portion of the spaced indicia of each sequence. The number of indicia printed on the first and second sides respectively of the circuit board may be determined after the circuit board is cut to the predetermined size. The circuit board may be accepted or rejected based upon the numerical determination against a qualification criteria.
