ELECTRIC CHARACTERISTICS MEASURING APPARATUS FOR IC DEVICE

摘要

PURPOSE: To make it possible to carry out test and measurement of various types of IC device by constituting a mechanism for bringing a tester into contact with an IC of a socket board, an interface board, and interconnecting board units. ;CONSTITUTION: An IC device D is discharged from a magazine at a loader section 3 and when the IC device arrives at a vertical shoot 5b through an inclining shoot 5a, it is positioned and connected with the contact mechanism 10 in a test head 2a in order to perform test and measurement. The contact mechanism 10 is constituted of three independent and mutually detachable members, i.e., an interface board 11, a plurality of interconnecting board units 12, and a socket board 13. A wiring pattern is formed on the surface of the interface board 11 whereas pin connecting parts are provided on the rear surface. Lead pins of the device D are inserted into the IC socket 14 on the socket board 13. In case of same outline different type device D, only the interface board 11 is required to be replaced.;COPYRIGHT: (C)1994,JPO&Japio
