Abstract:
1. A plunge transport mechanism for an electronic device test-handler grips and carries a device under test (DUT) in a first direction from a pick-up point to a test site where the DUT is driven into electrical connection with a test circuit via leads on the DUT that each align with and contact an associated connector at the test site, comprising: a drive that reciprocates between a retracted and an extended position, a vacuum suction source, and an elongated probe extending generally in said first direction from one end operatively connected to said drive to a tip and moving with said drive between said retracted position and said extended position, said probe operatively connecting said vacuum source to said tip that is proximate the DUT at the pick-up point such that the DUT at said pick-up point is gripped by said vacuum suction in a fixed position with respect to said probe during the operation of said drive and probe to carry the DUT along said first direction to the test site and into electrical connection with the connectors of the test circuit.
