Printed circuit board testing apparatus

摘要

A printed circuit board testing apparatus includes a first measuring system for determining a relative position between a circuit board carrying table and a test head with respect to two dimensions and an angular direction, a second measuring system for determining a relative position between the table and a circuit board carried by the table with respect to two dimensions and an angular direction, and a drive system for bringing the table and the test head into a first relative positional relationship for the testing of the circuit board in accordance with the relative positions determined by the first and second measuring systems.
