Abstract
Electrical sockets are positioned for insertion in holes in a circuit board by means of a sheet of a bendable plastics having an array of apertures in some of which the sockets are inserted. Each socket has a knurled region around its upper end just below a flange. The flange is undercut to give it a sloping lower surface and a peripheral edge that bites into the upper surface of the sheet. Ultrasonic energy is used to cause the sheet material around the sockets to flow into close contact with the terminals. The assembly of the sheet and sockets is used to insert the sockets in the circuit board following which they are soldered in place and the sheet is removed by pulling back from one edge over the sockets.
