ABSTRACT:
A system is disclosed for checking on the presence or absence of inserted leads of a component into the openings of a printed circuit board. The system is utilized within a component insertion machine wherein a plurality of optical lead sensors are preferably located within the cut and clinch mechanism. A computer system associated with the optical lead sensors compares the optical readings of the lead sensors with predefined data relating to the presence or absence of leads for each particular component being inserted.
