ABSTRACT:
A board fixturing system employed in an automatic in-circuit tester is vibrated at a sub-ultrasonic frequency that is in substantial close proximity to a resonant frequency of at least a major portion of the fixturing system to improve the probability of establishing good electrical conductivity between the probes of the automatic in-circuit tester and predetermined contact locations on the board under test.
