Patent number: 9897628Abstract: A method and apparatus for docking a test head to a peripheral. A docking pin (150) is moved past a projection (803) in a catch (802). The docking pin is further moved until the catch rotates and the projection in the catch engages a notch or indentation (152, 156) in the docking pin. A piston (620) is moved on to the catch so that the catch is prevented from rotating. The piston is further moved so that the test head is docked to the peripheral.Type: GrantFiled: September 18, 2014Date of Patent: February 20, 2018Assignee: inTEST CorporationInventors: Christopher L.

Publication number: 20140317453Abstract: A method and apparatus for docking an electronic test head with a peripheral, which positions devices for testing. Exact-constraint alignment features, also sometimes known as kinematic features, are incorporated to provide repeatable positioning of the test head in three degrees of freedom with respect to the docking plane of the peripheral. A distinct alignment feature is used to provide planarity and to establish the required docked distance between the test head and the peripheral. The exact-constraint alignment features are mounted compliantly to enable them to position the test head in the plane while the test head is away from its final docked distance and to maintain that position as the test head is moved to its final docked position.Type: ApplicationFiled: July 11, 2012Publication date: October 23, 2014Applicant: INTEST CORPORATIONInventors: Alyn R.
