  • PLGA test handler throw measuring unit
    Patent number: 6035731
    Abstract: A handler throw measuring unit (HTMU) for calibrating a test handler that handles an integrated circuit package. The throw measuring unit includes a plurality of pogo pins that are coupled to a base plate and a spring plate. The pogo pins are deflected when a test handler pushes the spring plate. The HTMU has a gauge that is coupled to the spring plate to measure the amount of pogo pin deflection. The amount of deflection can be provided on a numerical readout. An operator can incrementally move the test handler until the readout provides a desired value.
