Detector And FPA Testing

Santa Barbara Infrared, Inc. (SBIR)

The FPA Test Set (FPATS) interface to the detectors under test (DUT’s) is via a custom pedestal plate which provides both a conductive heat path to both the individual DUT’s as well as the field of view limiting aperture plate. This custom pedestal plate protrudes through the customer provided DUT interface printed circuit board (PCB) and makes physical contact with the rear of the DUT packages and the aperture plate when the FPATS is in the closed position. The pedestal plate is mounted to the ambient source plate and its temperature is actively driven by this subsystem.
