ABSTRACT:
An apparatus for determining lead integrity of DIP devices, wherein the leads of the DIP devices extend from a track for supporting the DIP devices during passage through the apparatus. Included is a transmitter for the transmission of a signal, positioned so that the leads of the DIP devices traveling on the track intersect the transmitted signals and a receiver for receiving and converting a transmitted signal to an electrical signal, positioned so that as the leads of the DIP device intersect the transmitted signal, the receiver generates an electrical signal reflective of the intersection for determining the integrity of the leads based upon the electrical signal. The receiver includes receptors positioned on either side of the track such that each receptor receives the transmitted signal intersected by the leads as the DIP devices travel on the track. The receptors are arranged wherein a first receptor is oriented upstream along the track and wherein at least two other receptors are oriented such that one is further than the other from the track in order to receive signals which intersect the leads at at least two spaced points therein. Both other receptors are downstream in the direction of travel of the DIP devices.
