A system was developed as part of a MICOM Manufacturing Methods and Technology (MM&T) contract to demonstrate the applicability of thermal scanning to testing electronic circuit boards and hybrid circuits on the production line. This paper presents a description of the test equipment outlining its hardware, software, test methodology, applications, capabilities, and limitations, and gives a summary of test results. A short discussion of the probable future of thermal scanning as an electronics test method for printed circuit boards and hybrids is also included.
