The Promex Story

Our mission is simple: solve your complex component assembly challenges. Promex has a long history in Silicon valley dating back to its founding in 1975. The company is privately held and has been under current management since 1995.In 2008, Promex pivoted to focus on the unique demands of the medical device and biotech market. Offering biotech instrument & medical device companies a low-risk path from feasibility prototype development through to full production. All in a single fully integrated US-based component assembly facility located in the heart of Silicon Valley.

From small-scale prototype production demonstrating the viability of your basic technical concept, through to scaling those processes into full production, Promex offers a fully integrated suite of services.

With a single partner, you can move from fabricating simple combinations of parts and measuring the result to eliminate development risks, through to full production. Meeting all the necessary requirements for FDA compliance and full manufacturing process validation, while still meeting rigorous cost requirements.

Promex CEO Dick Otte says, “it’s not unusual for companies developing complex devices to come to us after other providers failed to meet their IC packaging and assembly requirements.”

Let us know how we can turn your concept from working prototype to full-scale production.
