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.
THE NINJA WAY
Ninja Circuits is a flexible, fast, and skilled pcb assembly manufacturer dedicated to developing the best and quickest pcb assembly prototypes in the USA. We offer exceptionally fast pcb assembly prototypes to engineers and innovators developing new products to improve and enhance our lives and the world we live in. Ninja Circuits is proud to be based in the USA, which allows Ninja Circuits to provide excellent communication, on-time delivery, quick turn PCB assembly, and responsive customer service.


Flexible
Flexibility is our strength. No two customers are alike. Ninja will tailor our services to your needs to provide you with the desired outcome for your project.


Fast
Ninja Circuits knows that the culmination of your project design is a working prototype. Waiting weeks or months for validation is not only frustrating but impedes schedules and time to market and is unacceptable. Ninja can provide you a quality product in as short amount of time possible.


SKILLED
Our personnel are trained with skills on par with anyone in the EMS industry. A poorly assembled product is a failure. Ninja delivers fast AND quality products every day and will ensure your project needs are met.
OUR certifications
Ninja Circuits is committed to providing quality to customers. Certifications, training, and experience are what we take pride in at every step of the way for every project.
WHAT OUR CUSTOMERS SAY
We appreciated the quick and creative response you provided in building this product. I was concerned about the robustness of this assembly, but you found a solution that secured the components in the box sufficiently.
