Company History

Prototron Circuits, Inc. started operations in July of 1987 to serve the local electronics manufacturing community by providing a source for quick turn Printed Circuit Boards. Printed Circuit Board manufacturers typically were offering completion of orders within a 4 to 6 week time frame. Prototron Circuits made a commitment to offer much quicker and more flexible delivery schedules, typically 5-working days and as fast as 1-day. This commitment has drawn attention from the local electronics industry's research and development departments as a service that operates as an extension of their business. This service has brought about a partnership with the industry that is relied upon to rapidly develop today's newest technologies.

As a Printed Circuit Board Manufacturer, Prototron Circuits strives to make technological advances based on the demands and changing requirements of its customers and technology. These advances have included the manufacturing of multilayer printed circuit boards, up to 30 layers, minimum trace width's of 0.003", minimum drilled hole diameter of 0.006", and optional plating finishes such as full body and immersion gold. In 1996, Prototron added a photo-plotting and CAM/Engineering department to further assist our customers with concurrent engineering via CAM software to ensure quality before a design is released for manufacturing.

In January of 1997, Prototron Circuits acquired Cir-Quick, Inc. of Kirkland, WA making Prototron the largest prototype printed circuit board manufacturer in the Northwest with over 25,000 square feet of manufacturing space.

In January 1999, Prototron Circuits acquired Southwest Circuits, Inc. of Tucson, AZ. The newest member of the Prototron family is doing business as Prototron Circuits - Tucson. Prototron Circuits - Tucson is a MIL-SPEC shop offering our military and commercial customers fast-turn capabilities with experience in manufacturing Teflon, Duroid, PTFE and other specialty materials.
