Abstract
A test socket assembly, useful in association with a thermal control unit (TCU) used to maintain a set point temperature on an IC device under test, has alignment holes with bushings that are secured within the alignment holes by using retaining pins. The retaining pins can be easily screwed in and out of the socket. This provision allows the bushings to be replaced easily as they get worn out or deformed from repeated testing.
