  • Temperature regulator for burn-in board components
    Patent number: 5582235
    Abstract: The present invention is directed to an apparatus suitable for regulating, with an impinging flow of gas, the temperature of an electronic component under thermal stress testing at selected temperatures. The apparatus comprises a sensor which senses the temperature of the electronic component and provides an electrical signal representative of sensed temperature to a controller. A gas flow regulator is used to control flow directed to impinge the flow of gas upon the electronic component as necessary to adjust the temperature. The gas flow regulator ms controlled by the controller which operates the regulator so as to adjust the temperature of the electronic components.

  • Method for burn-in of high power semiconductor devices
    Patent number: 5579826
    Abstract: A thermal control system for use with a burn-in system, the thermal control system capable of delivering a thermally preconditioned liquid to a plurality of semiconductor devices during burn-in. The thermal control system comprises a liquid reservoir containing a liquid, a pump, and a plurality of spray nozzle arrays. The liquid contained in the liquid reservoir is thermally preconditioned through the use of a heating element and a cooling element and the temperature of the liquid provided to each spray nozzle array is individually controlled through the use of a pipe heating element. The liquid is collected and returned to the liquid reservoir after being sprayed on the semiconductor devices.
