CircuitHub

CircuitHub is a manufacturing service focused on on-demand circuit board assembly. Rather than acting as a marketplace or broker, it operates its own factory in Massachusetts, called The Grid, and sells capacity directly through the site. The core promise is rapid, low-cost production for prototypes and production batches, with instant quoting and turnaround starting from three days.

The distinguishing feature is how The Grid handles variety. Conventional lines are configured for one design at a time, so switching products costs setup time. At CircuitHub, levitating movers carry each board and its parts between robots that print paste, place components, solder, and inspect, and every board takes its own route. That removes changeovers and per-design setup, which is why high-mix electronics becomes practical.

The service is aimed at fast-moving robotics companies and similar hardware teams, including EV makers, AI labs, and established tech companies using it for test stations, tooling, R&D boards, and production batches. Engineers who need repeated small runs of different designs fit best.

To use it, start by checking the published PCB stackups, design rules, and certifications so your files match the process, then request an instant quote and upload your design. Because setup is not charged per design, batching different boards together is worth considering. Overall, CircuitHub is a strong fit for teams that value speed and design variety over single-product mass producti
