The OPTEK Innervision x-ray inspection and measurement systems from Operations Technology Inc. are suitable for multilayer printed circuit board applications. They allow the user to view and measure metal layers inside laminated or molded materials. In addition, gaskets and other flat structures can be probed to determine the location of reinforcing material and conductors. The systems feature two 17-in. color monitors and Windows-based metrology software, and provide ±5-µm positioning and measurement accuracy.
