ABSTRACT:
An apparatus for facilitating zero-insertion of a burn-in test probe having a probe head. The zero-insertion apparatus includes a triggering mechanism, a pressing mechanism, and a sensor which are disposed within the burn-in test probe to facilitate a damage-free insertion of the probe head into an IC socket having a zero-insertion rim. As the probe head is inserted into the socket, the pressing mechanism, being in its locked position, compresses the zero-insertion rim which retracts the socket contacts to allow the probe head to enter the socket unencumbered. When the head is completely in the socket, the sensor becomes actuated. The actuated sensor allows a user to then unlock the pressing mechanism which causes the zero-insertion rim to spring back to its original, undepressed position. The socket contacts revert back to their undepressed position and solid contact is made between the probe head and the contacts.
