ABSTRACT:
An apparatus and method for the rapid switchover between different height modules in an automatic module testing and handling machine. The multi-chip module (MCM) handling apparatus comprises a bottom rail and a guide rail which has an upwardly extending wall and an outwardly extending flange which form a channel. This channel provides a passageway through which a MCM of a first thickness can pass laterally such that the first MCM is in contact with the top surface which positions contact nodes provided on the first MCM at a predetermined vertical position with respect to the top surface. This handling apparatus further comprises a removable justifying plate (RJP) which is removably attached within the first channel, thereby forming a second channel. This second channel provides a passage way through which a MCM of a second thickness, which is less than the first thickness of the first MCM, can pass laterally. Thus, the second MCM is in contact with the upper surface of the RJP, thereby positioning contact nodes provided on the second MCM at substantially the same predetermined position with respect to the top surface, as the first MCM.
