Safety and Security PCB Assembly

We're Experienced in Building Safety and Security PCB Assemblies

When you're designing for critical systems like alarms, access control, fire detection, or surveillance, precision matters. At Ninja Circuits, we recognize the work that goes into every layout and schematic. Our role is to match that effort with careful, high-quality assembly on time, every time. We specialize in safety and security prototypes built in small batches, typically 1 to 10 units, with fast turnaround and expert oversight. With three decades of hands-on experience, IPC-trained technicians, and ITAR-ready protocols, we know how to deliver reliable assemblies that help you move forward with confidence.

Safety & Security PCBA Applications We Support

Alarm Systems


From intrusion detection to silent panic alarms, we assemble boards that drive fast-response security systems. Our prototypes help you validate performance under real-world conditions.

Access Control


Controllers for secure entry points such as doors, gates, or facility checkpoints rely on dependable logic, timing, and performance. Our assemblies help you confirm functionality before full rollout.

Fire Detection


Smoke, flame, and heat detection circuits need to work on the first try. We deliver rapid prototypes that help ensure your fire safety designs pass the test.

Surveillance Hardware


Cameras, motion sensors, and networked DVRs all rely on fast signal processing. We help you build boards that meet tight timing and signal integrity requirements.

Testing Standards That Protect Mission-Critical Systems

Even in prototype builds, quality can’t take a back seat. At Ninja Circuits, we inspect every board with the same precision tools and mindset you’d expect from a production run. That includes microscope-level visual checks, 3D AOI to catch misalignments and solder defects, and X-ray analysis for leadless and BGA parts. 



For more advanced validation, we offer flying probe or fixture-based testing to confirm net continuity and isolation. Boards can be built to IPC-A-610 Class II or III and prepped with conformal coating, labeling, and serialization. These systems often operate in demanding environments, and we match our process to that level of risk.
