We're Experienced in Building High Tech PCB Assemblies

Every new generation of technology depends on someone turning an idea into working hardware. At Ninja Circuits, we work with the engineers alongside that progress, assembling complex, high-density prototypes for computing, semiconductors, consumer devices, and IoT systems. Our focus is precision assembly built on controlled processes, repeatable results, and attention to every detail that affects performance. Each board we assemble supports the products that keep people connected, informed, and productive. With more than 30 years of experience, IPC-certified technicians, and consistent process oversight, we deliver small-batch prototypes that perform as designed, assembled fast enough to keep development moving.

High Tech PCBA Applications We Support

Consumer Electronics

We assemble compact, mixed-technology boards that help engineers validate performance, connectivity, and power efficiency in next-generation devices.

Semiconductors

Prototyping for semiconductor control and test systems demands clean signal paths and repeatable solder accuracy. Our builds maintain precision across every layer.

Computing

Boards for data processing, embedded systems, and control logic require tight tolerances and thermal management. Our assemblies support early verification for stability and throughput.

IoT Devices

Miniaturized, low-power assemblies are critical to connected devices. We build and inspect secure, scalable, and robust prototypes that ensure signal integrity, reliability, and seamless integration.

Testing Standards That Support Cutting-Edge Designs

High-tech prototypes push the limits of component density and precision. Each board we assemble undergoes detailed inspection using 3D automated optical inspection to confirm solder quality and alignment, X-ray imaging for leadless and BGA components, and microscope-level review for every placement. We perform electrical testing through flying probe or fixture-based methods to confirm continuity and isolation. Assemblies can be produced to IPC-A-610 Class II or III and completed with conformal coating and serialization. Every inspection step supports the level of precision your design will require before moving to mass production.
