by Brain, Alfred E. and Barnard, Stephen T.
Technical Note 302
Institution: AI Center, SRI International
Address: 333 Ravenswood Ave, Menlo Park, CA 94025
This report gives a preliminary account of the construction of a low-cost laser system for providing data on defective solder joints on printed circuit boards. The system possesses high resolution, excellent signal-to-noise ratio, and a substantial depth of focus; the speed at which it produces data is limited only by the data rate of the computer input channel.
