You’re building a product that needs to detect motion or presence without being touched. A smart light that knows when someone’s in the room. A security sensor that triggers an alarm. A car that knows when a passenger is in the seat.

The Induction radar PCBA inside it decides whether your product can sense the world at all. Detection accuracy, false trigger rates, power consumption, and whether you pass EMC certification all come down to how this board is designed, built, and tested.

So where do you go to get that board built by people who understand what it takes?

At OPCBA, we’ve been manufacturing induction radar PCBAs for years as a core specialization. Whether you need standard 5.8GHz modules for smart lighting, or custom 24GHz assemblies for security, automotive, or industrial applications, we deliver radar PCBAs that perform consistently from first prototype to the millionth unit.

What Makes a Radar PCBA Different

Radar products fail in ways that ordinary PCBA work does not catch: inconsistent performance across batches, false triggers that frustrate users, certification failures that delay launches, and premature failures in the field.

RF Design That Works at Scale

We follow strict high-frequency design rules, and they are applied on every board we ship. 50Ω impedance control, optimized antenna layout, anti-interference circuit design.

Consistent detection range and sensitivity from board to board, batch to batch. That is what keeps detection range consistent from board to board.

Power-Optimized for Battery-Powered Devices

If your product runs on batteries, every microamp matters. Our radar PCBAs support microamp-level sleep mode current consumption.

You get reliable sensing without killing your battery life. Wireless occupancy sensors that last years, not months. Smart locks that don’t need weekly charging.

Built to Pass Compliance

We design for compliance from day one: FCC, CE, RoHS and REACH. Our design guidelines, material choices, and layout rules are all aligned with global regulatory standards from the start, and the same discipline carries into radar PCB design and build.

Faster time to market. Lower testing costs. And one less thing to worry about when you’re already juggling a thousand other launch tasks.

Rugged Enough for 24/7 Real-World Use

Your product won’t live in a lab. It will live in walls, ceilings, cars and factories, where temperature swings, humidity and electrical noise are normal. We build our radar PCBAs with high-stability components, high-frequency-grade materials, and IPC-compliant processes.

Fewer field failures. Lower warranty costs. Products that last as long as your customers expect them to.

Design and Manufacturing Standards

We control every step of the process, from early design reviews to final testing, so the next batch is not a gamble.

Early-Stage Design Optimization

We work with your team before you lock in the layout to get these right:

RF trace optimization → less signal loss, cleaner detection
Power supply filtering → fewer false triggers
EMC design → built in, not bolted on
Material selection → stable Dk, batch to batch

Manufacturing That Follows the Rules

PCB manufacturing to IPC-6012, with impedance testing and material certs for every batch
SMT assembly to IPC-A-610, with specialized process control for fine-pitch radar chips
Component sourcing from authorized global suppliers, with alternatives identified in advance if parts go on allocation

Testing That Catches Problems

Generic PCBA testing won’t cut it for radar. Every single board we ship goes through:

AOI after SMT: soldering defects, missing parts and misalignment
X-Ray for BGA and QFN radar chips: hidden joints that AOI cannot see
ICT: electrical performance, plus shorts, opens and wrong values
FCT: power draw, current and signal output
100% RF performance testing: microwave testing for detection range, sensitivity, signal strength and interference rejection.

For harsh-environment applications, we can also add thermal cycling, humidity testing, and vibration testing.

Where Radar PCBAs Get Used

Smart Home & Lighting (5.8GHz)

Smart ceiling lights, wall switches, occupancy sensors, appliances. Our radar PCBAs detect micro-movements for true static presence sensing, so a person sitting still is still detected.

Security & Intrusion (24GHz)

Perimeter protection, alarm triggers, camera wake-up, outdoor security. Long-range detection with anti-false trigger design so pets and moving trees don’t set off alarms.

Automotive Electronics

In-cabin presence detection, rear collision warning, automatic trunk opening. Automotive-grade components, AEC-Q100 compliance, wide temperature range (-40°C to 85°C).

Industrial Automation & Safety

Equipment proximity detection, personnel safety guarding, material level sensing, AGV obstacle detection. Rugged design with strong noise immunity for factory environments.

Healthcare & Medical

Non-contact vital sign monitoring (breathing/heart rate), fall detection, patient monitoring. Ultra-high sensitivity to micro-movements, low EMI to avoid interfering with other medical gear.

Custom Services

We don’t just sell standard modules. We build what you need:

Custom frequencies: 5.8GHz, 24GHz, 77GHz, other bands on request
Tailored performance: optimized sensing range, sensitivity, power consumption for your specific use case
Full turnkey: schematic design, PCB layout, prototyping, mass production and testing, all handled in house
Flexible volumes: prototype batches to high-volume production, same quality standards
Compliance support: we help you navigate FCC, CE, and other regional requirements
Final assembly: box build services if you want a complete end-to-end solution

Working with OPCBA

A partner who understands the sensing technology behind the board is harder to find than a supplier who can populate it.

At OPCBA, we’ve been delivering end-to-end PCBA solutions for years, across automotive, industrial, medical and consumer electronics. From PCB fabrication and component sourcing to SMT assembly, rigorous testing, and even final box build, we handle it all under one roof. That means you get consistent quality, shorter lead times, and a single point of accountability for your entire project.

Our in-house engineering team speaks your language, whether the project is high-frequency radar or another complex PCBA. Our testing equipment goes beyond generic validation, and our quality control system is built around the one thing that matters most: consistency, from prototype to million-unit production.

If you’re tired of projects that work in the lab and fail in production, or suppliers who nod along but do not understand your technology, talk to us.
