PCi started in the Spring of 1977 and was incorporated April 1, 1977. Our first order was from the University of Minnesota, for 150 boards at $18.00 each. We were certified to Mil-P-55110 and built many boards for Litton Guidance and Control, and Teledyne.

In the ‘80’s PCi built almost every kind of circuit board on the market: rigid, flex, single sided, double sided, multilayer, polyimide, BT, Teflon and metal core boards. In 1982 PCi built their first rigid flex circuit board, a simple two layer laminated rigid flex that was used as a laser bore site for a helicopter mount, in two years time PCi was the first fabricator certified to Mil-P-50884 for Rigid Flex, and the complexity and demand for difficult Rigid Flex boards began to grow.

Early customers that helped encourage the technology were Litton, Eaton, Bendix Aerospace, Collins Radio, Delco, Honeywell, and ITT Avionics. All names that used Rigid Flex to advance the technology of their products with increased reliability, functionality, and reduced size and weight.
