We're Experienced in Building Industrial PCB Assemblies

Industrial systems rely on hardware that performs under constant stress. At Ninja Circuits, we build the prototypes behind those systems, like the control boards, drives, and monitoring circuits that keep factories efficient and precise. Our focus is dependable assembly built for harsh, high-demand environments where vibration, heat, and electrical noise are constant. Each assembly supports technology that drives output, monitors process accuracy, and improves efficiency across demanding environments. With more than 30 years of experience, IPC-certified technicians, and ITAR-ready documentation, we deliver small-batch industrial prototypes that hold up during rigorous testing and are ready to scale in production.

Industrial PCBA Applications We Support

Machinery Controls

Boards that manage motors, drives, and actuators must maintain precise timing and electrical stability. We assemble prototypes that let you confirm performance before full-scale deployment.

Robotics

Servo control and feedback systems depend on clean signal paths and tight mechanical integration. Our assemblies support accurate movement and fast iteration in early development.

Factory Automation

Control logic, PLC backplanes, and communication modules require consistent builds for validation and endurance testing. We help you verify functionality across complex systems.

Sensors and Monitoring Equipment

Industrial sensors often face wide temperature swings and electrical noise. Our prototypes are assembled for stability and repeatable performance during calibration and testing.

Testing Standards that withstand Harsh Environments

Since industrial hardware doesn’t operate in clean rooms or climate-controlled labs, every board we assemble is inspected and verified to withstand demanding conditions. We use 3D automated optical inspection to confirm solder alignment, X-ray imaging for BGA and leadless components, and microscope-level checks for precise placement. Flying probe or fixture-based testing ensures electrical continuity and isolation across mixed-voltage designs. 



Assemblies can be produced to IPC-A-610 Class II or III and finished with conformal coating, labeling, and serialization for traceability. These steps confirm that each prototype can handle the physical and electrical stresses expected in industrial use.
