Abstract
A heating apparatus for heating a DUT is provided. The apparatus contains at least one DUT contact area adapted to be in contact with a single DUT and a plurality of discrete heating elements, such as surface mount resistors, in thermal communication with the DUT contact area. The apparatus also contains an enclosure enclosing the heating elements and a heat exchange fluid passage bounded by an outer surface of the heating elements and an inner surface of the enclosure.
Claims51
A heating apparatus, comprising:
- at least one DUT contact area adapted to be in contact with a single DUT;
- a plurality of discrete heating elements in thermal communication with the DUT contact area;
- and
- a heat exchange fluid passage.
A heating apparatus, comprising:
- a plurality of discrete heating elements;
- an enclosure enclosing the heating elements;
- and
- a heat exchange fluid passage bounded by an outer surface of the heating elements and an inner surface of the enclosure.
A heating apparatus, comprising:
- at least one DUT contact area adapted to be in contact with a single DUT;
- a plurality of discrete heating elements in thermal communication with the DUT contact area;
- an enclosure enclosing the heating elements;
- and
- a heat exchange fluid passage bounded by an outer surface of the heating elements and an inner surface of the enclosure.
A heating apparatus, comprising:
- at least one DUT contact area adapted to be in contact with a single DUT;
- a first set of discrete heating elements in thermal communication with a first portion of the DUT contact area;
- a second set of discrete heating elements in thermal communication with a second portion of the DUT contact area adapted to heat the second portion of the DUT contact area to a lower temperature than the first portion of the DUT contact area;
- and
- a heat exchange fluid passage.
A method of making a heating apparatus, comprising:
- providing a DUT contact surface;
- mounting a plurality of discrete surface mount resistors on a portion of the DUT contact surface adapted to be in contact with a single DUT;
- and
- placing an enclosure over the resistors to form a heat exchange fluid passage bounded by an outer surface of the resistors and an inner surface of the enclosure.
A method of testing a DUT, comprising:
- placing the DUT in contact with a DUT contact surface;
- providing an electrical testing input signal to the DUT;
- receiving an electrical testing output signal from the DUT;
- heating the DUT witha plurality of discrete heating elements located in thermal communication with the DUT contact surface;
- and
- providing a heat exchange fluid into a heat exchange passage adjacent to the plurality of discrete heating elements.
