About

CircuitHub is an on-demand electronics manufacturer that runs an automated factory around a software platform for rapid printed circuit board assembly. Engineers upload EDA design files from tools such as Altium, EAGLE and KiCAD and get an instant online quote covering bare board fabrication, parts and assembly. The company builds runs from single prototypes up to production volumes, with full turnkey fab and assembly in three days by default, drawing on a shared inventory of common components. Its factory is in South Deerfield, Massachusetts, and it also operates in Europe.

Replaces the quote-and-email cycle of traditional contract manufacturers with an automated platform that prices a board straight from its design files and a factory built around that software, delivering full turnkey assembly in days instead of weeks.
