Since 1995, the company, which is located east of Lake Tahoe in Carson City, Nevada, has been actively involved in the development, manufacturing and sales of analytical wafer probing equipment, photomask inspection stations and board test systems for signal integrity testing. PSI's focus has been, and continues to be, providing feature rich products at fair prices. The company can do this not only because of the breadth of experience but because its business model requires keeping its overhead expense at levels much less than its competitors.
