Abstract
A system has been developed under contract from the U. S. Air Force for noncontact testing of printed wiring assemblies (PWAs) in depot level environments. The testing is performed by sensing the thermal image of the powered PWA and comparing it to a thermal image from a known good PWA. Designed around a central host computer, the system is completely automatic and quite operator interactive. The complete system integrates a host computer with an Infrared Scanner, a Digital Image Processor, a trackball controller, a TV monitor, a video printer and a fixture for mounting the PWA under test.
