Abstract
Abstract A rotatable generic connector assembly for testing an integrated circuit package has an integrated circuit connector that can be connected to the integrated circuit package leads in any of a plurality of possible orientations; a second connector having a pattern of electrical contacts arranged in a symmetrical pattern (e.g. a square grid) about a center point; a flexible circuit providing a plurality of conductors from the integrated circuit connector contacts to the second connector contacts; and a test equipment connector assembly having a pattern of electrical contacts for engaging the second connector contacts in any of a plurality of possible orientations. The odd symmetry of the pattern of contacts on the second connector allows the integrated circuit leads to be connected in the same order to the testing equipment connector regardless of the selected orientation of the integrated circuit connector in engaging the integrated circuit by selecting a corresponding predetermined one of the possible orientations for the test equipment connector in engaging the second connector. In addition, the test equipment connector can include an interchangeable transition board to provide an interface between the second connector contacts and a different contact pattern used by the test equipment.
