About Us Sierra Assembly Technology Inc. sprouted from humble roots in 1982, operating with one simple pick and place machine in a 7,000 square foot building. We have since more than tripled the square-footage of our working space, now running two fully automated SMT assembly lines in the 20,000 square-foot complex we call home. Our production has both expanded and become more efficient. However, we remain a small business at heart, with the versatility to accommodate a wide variety of customer needs, and the disposition to ensure these needs are met sufficiently. Over the years, we’ve worked with industries of all kinds — from those in government and healthcare, to the world of entertainment — and Sierra has proven, again and again, that we’re equipped to supply for any type of business. For more than 30 years, Sierra’s goal has been to build premier circuit board assemblies right here in our own local facilities. Whatever changes may come for our industry and for our company, we believe in American-made products and we believe in creating, and keeping jobs in America.
