Abstract: The present invention involves a method and apparatus for feeding axial lead components directly from a sequencer to an insertion head, while eliminating direct supplying of components to the insert head via a prededicated inventory such as reeled tapes or films having components attached thereto in a predetermined sequence. Preferably, an endless chain conveyor carries the components to the insert head in chain clips which positively retain the leads thereof while allowing centering of the bodies and electrical function testing of the components just prior to insertion of the leads into corresponding holes of a circuit board. Direct supply from a sequencer having a series of individually and programmably controlled dispenser heads provides for quick and flexible variation of an input sequence without manual intervention.

Abstract: Described is a machine for pre-gluing raw circuit surfaces of printed circuit boards (P.C. boards) at an adhesive station and properly positioning the P.C. boards at a placement station for placement of leadless electronic components (chips) onto the adhesive. A carousel provides program preselected vertical supply of taped components to a feeder assembly which feeds individual chips onto a nozzle of a turret-type vacuum head at a pick-up station. The turret-type head has four nozzles spaced 90.degree. apart about the central axis of the head. As the turret is rotated, a chip is transported by a nozzle, sequentially, from the pick-up station to a centering and testing station, a centering and orienting station, and a placement station. Located between the testing and orienting stations is a chip removal station for ejecting defective or inverted chips. Sensors are located at the adhesive and placement stations to detect defective P.C. boards so that they may be bypassed.

Abstract: A combination of a plate for exposure, such as a printed circuit board, having a pair of photosensitive layers formed on its opposite surfaces, and a pair of transparent frame plates between which the plate for exposure can be sandwiched, and which are each provided with a mask on its surface facing the plate for exposure. The plate for exposure is formed with a pair of apertures adjacent to each of a pair of opposite edges thereof. Each of the frame plates is provided adjacent to each of a pair of opposite edges thereof with a pin facing one of the apertures and a recess facing the other aperture. The pin on one of the frame plates faces the recess in the other frame plate. The pins are so sized and shaped that they can be easily fitted in, and removed from the apertures, and can hold the frame plates against displacement relative to the plate for exposure when fitted in the apertures.
