Scan test machine for densely spaced test sites

摘要

A scan tester for printed circuit boards capable of testing densely spaced test locations on the circuit board including a desk top robot having a test head positioned over the circuit board and movable in a three-dimensional plane. The test head includes a non-contact energy source such as a source of plasma located at an end of the test head for energizing the test locations of the printed circuit board. The printed circuit board is mounted on a test fixture having a plurality of translator plates and translator pins for contacting a second surface of the printed circuit board to translate test signals to an electronic test analyzer.
