Abstract
Abstract An apparatus for use in installing integrated circuit sockets on printed circuit boards. A frame, on which is mounted dispenser tubes loaded with integrated circuit sockets, is positioned at an acute angle and vibrated at low frequency, causing the integrated circuit sockets to slide down the dispenser tubes. A template, containing cavities to receive the integrated circuit sockets, is slidably mounted at the lower end of the dispenser tubes. As the integrated circuit sockets are discharged from the dispenser tubes, they fall into the cavities, pin side up. A printed circuit board is aligned above the loaded template and the two are clamped together causing the integrated circuit socket pins to pass through corresponding holes in the printed circuit board. The clamped printed circuit board and template are then rotated 180 degrees and the template is removed, leaving the integrated circuit sockets mounted on the printed circuit board.
