Roger Lang and his brother Kermit Lang started Circuit Assembly over 50 years ago with one goal in mind – to design and manufacture connectors. The Lang brothers spent the next 10-15 years in the Irvine, CA area perfecting their craft and branching out into custom cable assemblies.

As our company saw continued success throughout the 90s, we were able to grow our team here in Irvine as well as open our manufacturing plant in China in 1999. Having a team in China allowed us to take on more complex orders, as well as offer increased flexibility in pricing for our clients.
