Abstract
A system is provided for verifying defects in a printed circuit board (PCB). The system includes a base and a gantry apparatus affixed to the base. The gantry apparatus has first and second positioning apparatus adapted to move in perpendicular directions in a locating plane in response to control signals. A platen is located on a table on the base and is adapted to move from a first position extending from the base to a second position in registration with the positioning apparatus in a plane parallel to the locating plane. The platen is further adapted to receive the PCB, and includes an alignment mechanism to register the PCB with a preferred position thereon. An optical viewing assembly is mounted with the positioning mechanism for providing an optical image of a selected location of the PCB. The system also includes a controller for receiving signals identifying the PCB and selecting an associated data file from a computer memory having signals therein indicative of the address of the defects on the PCB. The controller provides control signals to the positioning mechanism to locate the optical viewing assembly at the address of a selected one of the defects.
