Abstract

An integrated circuit tester includes a fail-safe mechanism for moving an integrated circuit chip between an initial position where the integrated circuit chip is inserted into the tester, and a test position where the integrated circuit chips is actually tested. This fail-safe mechanism includes a motor and a shaft which the motor rotates to move the integrated circuit chip. An electronic control circuit can be included to automatically stop the motor when the integrated circuit reaches its initial position, or its test position; but if the control circuit fails to operate properly, then damage to the integrated circuit tester is prevented by the fail-safe mechanism.
