Rjc Liquid Power Module Test Fixture

The Analysis Tech Rjc Liquid-Power-Module Test Fixture is a semi-custom, high-performance liquid-cooled heat sink for thermal testing of high-power modular-devices at power dissipations of more than 3500 watts. This fixture is ideally suited for measuring junction-to-case thermal resistance and impedance on large power-module packages of all device types including IGBT mixed-modules, full and half bridges modules, and large MOSFET modules. Temperature controlled coolant water must be supplied to the fixture from a recirculating chiller. Each test-head is uniquely designed for a particular set of package dimensions although test heads are easily interchangeable with drip-free liquid connectors. Thus, this fixture base functions are a universal base for any package-specific Rjc Liquid-Power-Module test head.

A top-mounted combination plug/screw connector or the side-mounted edge-card connector provides convenient connections gate signals, kelvin connections, and Tj sense connections. This design allows the fixture to be quickly reconfigured for any part-type by swapping the part-specific, two-connector wiring harness.
