Abstract:
A testing apparatus for testing image sensing integrated circuits, said testing apparatus comprising:a test head adapted to receive an integrated circuit under test, the test head having electrical contacts for making electrical connections to the integrated circuit; a light source; a light source output arranged to shine regulated test light on a light sensing portion of the integrated circuit; a light box, said light box incorporating an electronic filter disposed in a path of light from said light source to be modified before reaching said light source output; controlling circuitry coupled to communicate with the integrated circuit by way of said electrical connections to control functions of the integrated circuit during testing; and dedicated processing circuitry coupled through a fast data channel to the integrated circuit by way of said electrical connections to receive output signals from the integrated circuit during testing, the dedicated processing circuitry being adapted to analyze the output signals for the purpose of determining whether the integrated circuit under test meets predetermined test criteria.
