Mission-Critical Manufacturing™
Process Capability

Calumet has been manufacturing printed circuit boards in the USA since 1968. Over the years we have learned a lot about making boards and building partnerships. Mission-critical manufacturing maintains the process capability required to produce highly-reliable printed boards with dock-to-stock performance you can rely on.

The following capability matrix is a snapshot of current, developing and planned process capabilities.
