ABSTRACT:
A mechanism for sensing whether the leads of a dual-in-line electrical component are in their proper position projecting through the appropriate openings in a printed circuit board. The sensor uses fiber optics to indicate whether the leads are properly positioned by using light reflected from the lead to activate a photo transducer which indicates to the computer controlling the machine operation whether the leads are properly positioned. The sensor fiber optics has light emitting and light receiving filaments operative parallel to the board surface so that the sensor only responds to the presence or absence of a component lead.
