Benchmark Electronics, Inc.
A maker of electronics for other companies, Benchmark builds printed circuit boards, systems, and precision metal parts in low-to-medium volumes for regulated fields like medical devices, aerospace and defense, semiconductor equipment, and industrial gear. It got its start in 1979 in Clute, Texas as a manufacturing arm of Intermedics, a medical implant maker, before being bought out and renamed Benchmark Electronics. A fun quirk: the company that once assembled pacemaker parts now helps build gear for everything from hospitals to satellites.
