Abstract
A test apparatus for testing a know-good die integrated circuit is disclosed. The test apparatus uses conductive straps extending across trenches. The straps align with bond pads on the integrated circuit. When the bond pads are brought into contact with the straps, the straps exert a counterforce in the opposite direction to ensure a good electrical contact while testing the integrated circuit.
