Method and apparatus for positioning an integrated circuit device in a test fixture
First Claim
1. In an integrated circuit ("IC") test system, which includes at least one IC chip having a plurality of contact pins (the "DUT"), and which includes a feed-through interface module, and which also includes an interface board for mounting the DUT, a method for positioning the DUT in the test system comprising the following steps:
- a. positioning DUT on the DUT interface board;
b. positioning a conductive spacer in contact with the DUT; and
c. attaching the DUT interface board with the DUT to the feed-through interface module so that the conductive spacer makes abutting contact with the feed-through interface module, and the DUT contact pins make abutting electrical contact with the DUT interface board.

Abstract
A method and an apparatus are disclosed for positioning an integrated circuit chip to be tested on a device-under-test ("DUT") interface board without using a hold-down plate and for attaching this interface board to a feed-through interface module so that the device being tested makes abutting contact with the feed-through interface module and so that the contact pins of the device being tested make abutting electrical contact with contact pin sockets on the DUT interface board. This arrangement provides a path for heat and ion dissipation from the chip being tested in a simple and elegant manner which also minimizes potential damage to the chip.
