Abstract
A semiconductor chip test jig for testing a chip 10 with 'gull-wing' leads 11 comprises a body 20 and a cover 30. The body 20 has sets of fins or combs 23 which engage with the leads 11 to locate the chip 10 in the horizontal plane; the cover 30 has a set of 'knife-edge' lead supports 35 formed to match a trim and form jig in the region of the leads 11 from where they emerge from the encapsulation of the chip 10 to their first bends; and the body 20 has a set of spring-loaded pins 24 which contact the leads opposite the lead supports.
