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 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. 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.
