Patent ID: 7276895

Claim:
Apparatus for establishing a distance between a test head having test head electrical contacts and a peripheral having peripheral electrical contacts, comprising a plurality of alignment features which are coupled to one of said test head and said peripheral; and a plurality of linear units coupled to the other of said test head and said peripheral for causing movement of at least one of respective docking surfaces of said test head and said peripheral towards and away from each other, an actuating member which, when actuated, causes actuation of said plurality of linear units to cause said movement of said respective docking surfaces, said alignment features and said linear units preventing said test head and said peripheral from being closer to each other than a docked distance, wherein, at said docked distance, said test head electrical contacts and said peripheral electrical contacts are in contact with each other; and a sliding unit for a) changing position of said linear units relative to said other of said test head and said peripheral or b) changing position of said alignment features relative to said one of said test head and said peripheral in order to change said docked distance.
