  • Patent number: 10401386
    Abstract: A structure and method for providing a contact pin between a device under test (DUT) and a load board which provides upper and lower contact point which are axial aligned is disclosed. The pin has an upper (30) and lower (32) section and a hinge (44/46) in between which allow flex of both upper and lower contact (24/26) which, but the axial alignment can provide a direct replacement for POGO pins but with greater reliability. It also includes a structure and method for removing upper pins 230 by use of a modified hinge 244a.
    Type: Grant

It also includes a structure and method for removing upper pins 230 by use of a modified hinge 244a. In an alternate embodiment, the lower section includes a leg extension 320 and a sliding contact land 360 which slides against an aperture in the housing. A spacer 342 provides space for decoupling components on the load board. The hinge may include a truncated cylinder 40b which is configured to permit remove of the upper pin without removal of the lower.

  • Patent number: 9476936
    Abstract: The IC test system provides a system and method for thermal management of test pins. A test pin array (22) in a pin guide (24) is mounted in a retainer (20) which is located between an IC wafer (12) which contains IC devices to be tested (DUT) and a load board (40) which provides pathways to test signals to the DUT. On the other side of the load board is a contact plate (50) which together with the retainer straddles the load board. Leg extensions (36) pass through the load board apertures (42) and provide a thermal circuit from the contact plate to the retainer and to the pin array. On the upper side of the contact plate is a cooling/heating system with a thermal electric peltier device (62) and a further heat exchanger (64) as needed. Holes (44) are provided in the legs (36) to provide a supply of dry air to the wafer and pin array to minimize condensation as a result of cooling effects.
