A plurality of integrated circuit lead clips having a circular top opening and four resilient planar tines are positioned in a holding fixture in a rectangular matrix array. A carrier strip including a plurality of equally spaced, transversely extending projections each having a generally rectangular cross-section is positioned above a row of clips positioned in the fixture. The strip is vibrated and then lowered to pass one projection into the top opening of each clip and through the four resilient planar tines. Vibrations of the projections at the same time the tips of the projections touch the clips causes the clip to rotate in the fixture so that the planar ends of the tines orient with respect to the four flat sides of each projection. The projections are pushed through the clips so that they are held to the projections by the resiliency of the tines. Once the clips are oriented and affixed to the projections on the carrier strip they may be installed directly into mounting apertures, such as plated holes in a printed circuit board, or inserted into oriented integrated circuit connector contacts.

A multiplicity of integrated circuit connector contact sockets mounted to a plurality of carrier strips are moved between pairs of orientation rollers with tails of the contacts protruding upwardly whereby an upper socket portion of one contact is aligned with an upper socket portion of a contact on a carrier strip in an adjacent row. A plurality of integrated circuit connector insulators having socket receiving apertures formed therein are held together in an array and placed over the contact tails with one tail being received within each aperture of an insulator. The carrier strips are simultaneously advanced beneath a work station wherein a tool presses the insulators downwardly to tightly fit the contact socket portions into the receiving apertures in the insulators. A shearing tool then severs the insulators in the array from one another except for the continued affixation of the contact sockets to the parallel carrier strips. The carrier strips are then moved through a stripping station comprising a block having parallel channels for receiving the carrier strips and a flat inclined upper surface wherein the carrier strips are restrained from vertical movement while the inclined ramp strips the insulator mounted contacts from the carrier strips to form completed individual connectors.

A tool for and a method of inserting a printed circuit board on to a contact assembly is described in which the board is positioned between opposing contact fingers by rotating the circuit board on an alignment pin so that solder pads on the circuit board are aligned with and positioned between the contact fingers one at a time.
