Abstract:
An apparatus for interfacing between a device tester and a first ball grid array packaged integrated circuit (BGA IC), the apparatus comprising:a nesting member having an upper surface including a test area defining a plurality of through-holes, and a positioning member fixedly connected to the upper surface and located adjacent to the test area, the nesting member also defining a plurality of guide holes; a fixed base located below the nesting member and including a plurality of guide shafts that are slidably received in the guide holes formed in the nesting member; a first adapter that is temporarily mounted on the upper surface of the nesting member, wherein the first adapter includes an outer peripheral edge that fits within the positioning member such that the positioning member resists lateral movement of the first adapter relative to the upper surface of the nesting member, and wherein the first adapter defines a central opening for receiving the first BGA IC such that the first BGA IC is positioned on a selected region of the test area.
