Multiple rigid contact solution for IC testing

摘要

A chip testing solution having two separate contacts: one to provide current and one to measure voltage. One contact acts as the force and other as sense, and with its unique short wipe stroke technology enables the electrical connection from the contact terminal of the device under test (DUT) to the loadboard without fail even after prolonged insertion/testing of the devices. The two contacts are in close proximity, but electrically isolated from each other. Each contact is made to electrically touch a single conductive lead/pad on the DUT thus forming a test connection. The two contacts; one on front and other on back, wiping on the lead/pads will generally be a “sense” probe, and a “force” used for making a Kelvin connection. The short contact is connected to the loadboard by means of an additional contact known as “interposer” extending through and top of the tall contact base body.
