  • Method and apparatus for establishing quick and reliable connection between a semiconductor device handler plate and a semiconductor device test head plate
    Patent number: 6586925
    Abstract: A new method and apparatus is provided to quickly and reliably position, connect and dock a handler plate with a test head plate of a Universal Docking System. A handler plate is provided with roller assemblies while a test head plate is provided with matching receiver block assemblies. The roller assemblies are aligned with and partially inserted into the receiver block assemblies. Part of the roller assembly is mechanically engaged by the receiver block assembly, a mechanical linkage between an operator handle and the receiver block assembly allows the operator to complete the locking of the test head plate with the handler plate thereby at the same time establishing electrical contacts between arrays of pins that are mounted on surfaces of the handler base plate and the test head.
