Jim Rathburn may not be a household name in the printed circuit industry, but maybe he should be. A self-styled serial technologist and innovator, Rathburn holds more than 80 patents covering the gamut of high-density printed circuits, materials and semiconductors.

As founder and president of Precision Circuit Technologies, Rathburn helps commercialize the Minneapolis area company’s high-performance, high-density printed circuits, electrical interconnects, and advanced materials for the next generation of semiconductors, electronics, and systems.

He discusses PCT's technologies, in particular with liquid crystal polymer, and its use of both additive and conventional processes to build lines and spaces down to 6 microns. He also details PCT's zero-discharge processing, and licensing approach.
