Our Story/History

Over 45 Years of Service

We started making printed circuit boards back in 1972 with a commitment to total customer satisfaction, and have been exceeding customer expectations ever since. Our rapid growth is, we believe, a function of our dependability to deliver high-quality printed circuit boards on time year after year.

What’s In A Name:

I know it seems logical that we chose the name Sunstone because it is the Oregon state Gemstone, but there is more than what meets the eye. As part of the transition to the new owners and management in 2005, our company went through a branding exercise.

During that exercise, we landed on the following core concepts to help with the new name. “Sun” represents a new beginning, a shining start and “Stone” represents the solid foundation already established.

We continue to profess that each day is new. We will embrace it and grow with our solid, experienced team in place.
