Induction radar PCBA

Induction Radar PCBA | High-Reliability Microwave Sensing PCB Assembly

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 isn’t just another component—it is your product’s ability to sense the world. 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 actually understand what it takes?

At OPCBA, we’ve been manufacturing induction radar PCBAs for years—not as a side offering, but 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 Our Radar PCBA Different (And Why It Matters)

Generic PCBAs are designed to connect components. Ours are engineered to solve the real-world problems that kill radar products: inconsistent performance across batches, false triggers that frustrate users, certification failures that delay launches, and premature failures in the field.

RF Design That Actually Works at Scale
We follow strict high-frequency design rules—not just on paper, but on every board we ship. 50Ω impedance control, optimized antenna layout, anti-interference circuit design.

What that means for you: Consistent detection range and sensitivity from board to board, batch to batch. No more “prototype worked, mass production failed.” No more field returns because half your boards couldn’t see past two meters.

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.

What that means for you: 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 (Not Just Hope)
We design for compliance from day one—FCC, CE, RoHS, REACH. Our design guidelines, material choices, and layout rules are all aligned with global regulatory standards from the start.

What that means for you: 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’ll live in walls, ceilings, cars, factories—places with temperature swings, humidity, electrical noise. We build our radar PCBAs with high-stability components, high-frequency-grade materials, and IPC-compliant processes.

What that means for you: Fewer field failures. Lower warranty costs. Products that actually last as long as your customers expect them to.

How We Build Them: Our Design & Manufacturing Standards

We control every step of the process—from early design reviews to final testing—so you’re not crossing your fingers hoping the next batch works.

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 fabrication 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—no counterfeit risk, with alternatives ready if parts go on allocation

Testing That Actually Catches Problems
Generic PCBA testing won’t cut it for radar. Every single board we ship goes through:

• AOI after SMT—catches soldering defects, missing parts, misalignment

• X-Ray for BGA/QFN radar chips—inspects hidden joints AOI can’t see

• ICT—verifies electrical performance, catches shorts/opens/wrong values

• FCT—validates power draw, current, signal output

• 100% RF performance testing—microwave testing for detection range, sensitivity, signal strength, anti-interference. Every board. Not sampling. Not “looks good.”

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

Where Our Radar PCBAs Actually 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—not just waving-your-arms detection.

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: Not Just Off-the-Shelf Modules

We don’t just sell standard modules. We build what you actually 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, testing—we handle it all

• 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

Why Work with OPCBA?

There are a lot of PCBA manufacturers out there. But a true one-stop partner? That’s harder to find.

At OPCBA, we’ve been delivering end-to-end PCBA solutions for years—not just for induction radar, but 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 you’re designing high-frequency radar or any other 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 don’t actually understand your technology—talk to us.
