Box Build & System Integration
Chassis and enclosure assembly, cable and harness build, firmware loading, and serialized system integration. A finished, tested product, not just a populated board.

A Finished System, Not Just a Populated Board
Overview
Box Build & System Integration takes your assembly the rest of the way: chassis and enclosure assembly, backplane integration, cable and wire harness build with internal routing and connector installation, firmware loading and component programming, and serialized system builds with full documentation, out of our Burnsville, MN facility.
