Abstract
A test clip is provided, of the type that has multiple contacts that engage the leads of an IC (integrated circuit) device with closely spaced leads, which can be constructed reliably and at low cost. The test clip includes a flat flexible cable (52, FIG. 5) mounted on the clip housing (30), the cable having parallel conductors mounted on an insulative layer. The lower ends (58) of the conductors serve as lead-engaging contacts, and have exposed inner surfaces that directly engage largely vertical parts (60) of the IC device leads. A stiffener (70) formed by a sheet of stiff but flexible material, is attached to the lower portion of the cable on its outer surface, the stiffener having a lower portion that biases the lower ends of the conductors towards the leads. A circuit board (40) is mounted on the clip housing to lie in a horizontal plane, and has contact pads (80) on its lower surface. The flexible cable is bent so its upper end extends horizontally and has exposed upper conductor ends (92) that connect to the pads on the lower surface of the circuit board, the pads being connected to contact elements (36) of connectors on the upper surface of the circuit board.
