Abstract
Abstract Provided is a universal decoder test board (UDTB) capable of performing the package interface and pin scrambling functions of a conventional DUT board with a variety of different package designs. The UDTB is designed such that it is capable of interfacing with a variety of different tester interface boards, each tester interface board associated with its own hardware manufacturer tester. The UDTB significantly reduces the time and expense invested in test boards required for testing semiconductor device packages for a variety of different manufacturers'platforms by allowing a given package type to be tested with a plurality of testers on the same UDTB.
