ABSTRACT:
A protective fixture for a flat chip carrier comprises a flat fixture body having a recess in one surface thereof which receives the body of the chip carrier so that the leads extending from the edges of the chip carrier project towards the edges of the fixture body. Tool clearance openings are provided which extend through the fixture body and are located between the chip carrier and the edges of the fixture body so that the leads extend into and partially across the clearance openings. The tool clearance openings permit the performance of various operations on the leads and on the integrated circuit such as trimming and forming of the leads and testing of the circuit in the chip carrier. The leads are fully protected and it is not necessary to remove the chip carrier from the fixture until it is assembled to a circuit board or the like.
