ABSTRACT:
An automatic test apparatus for circuit boards in which the system is divided into an assembly sub-system, and a control sub-system. Probes are transferred from a magazine to a test head that is comprised of a base plate and probe plate along with associated support tables that enable X and Y translation of the probe plate to accommodate random pattern test points. The assembled test head is conveyed to a test station wherein a pressure plate contacts the circuit board being tested which in turn contacts the test head to carry out testing. The control sub-system covers control of all aspects of probe transfer including control of ejector members for probe transfer.
