Abstract
There are over a dozen commercially available automatic visual inspection devices for quality control on multilayer printed wiring boards (PWBs) and printed wiring phototools. Among the many early prototypes built for commercial evaluation was the PWBIS II unit built in our laboratory with sponsorship of the Robotics Institute and Westinghouse Electric Corporation. The design was done in collaboration with Dr. Mark Friedman, with engineering support from Drew Anderson, Robert Berger, and Dan Nydick of the Robotics Institute. This report summarizes the operation and methods employed in that device. The focus is on measurement embodied in the device itself and on the problem of the evaluating a PWB inspection station's performance. In previous papers we alluded to this device and how it operated [10], but did not discuss its design and performance. This device, which we called "PWBIS II" for 'Printed Wiring Board Inspection Station II', was decommissioned by Westinghouse approximately six months ago. It has been moved back to the laboratory and is available now for research uses.
