Abstract: A device for fitting electronic components and their respective connecting leads into the proper holes in a circuit board. The device includes an illuminating matrix with a grid size small enough to illuminate any desired hole in the printed circuit board, which matrix is mounted on a carriage movable with respect to the circuit board. The matrix is movable along the length of the carriage such that the holes in the illuminating matrix may be selectively illuminated after the carriage and matrix are moved to align the matrix holes with the desired printed circuit board holes.
