When developing electronic products for the medical industry, consistency isn’t just a goal — it’s a requirement. One defective board could mean more than just a return; it could impact patient safety and regulatory approval.
At Fumax, we recently partnered with a medical device startup to scale their design from an early prototype to 10,000 fully tested production units — all while maintaining identical electrical, mechanical, and performance results across every batch. Here’s how our integrated Electronic Design, PCB Assembly, and Electronic Manufacturing workflow made it possible.
The customer arrived with a prototype that worked — but only sometimes. Built by hand, each board showed small variations in signal noise and sensor calibration. The problem wasn’t in the schematic itself; it was in inconsistent assembly and component tolerance drift.
For a device that would eventually go through ISO 13485 medical certification, this kind of variation was unacceptable.
Our task: reproduce their design at scale with zero deviation in performance metrics — even as we transitioned from manual soldering to full SMT (Surface Mount Technology) production.
The first step was a detailed BOM and Gerber review. Our engineering team checked for:
By making these refinements before mass production, we reduced potential risks that could cause drift between early and later batches.
Next, we executed a pilot run of 200 units — a crucial bridge between R&D and full-scale manufacturing. During this stage, our process engineers fine-tuned:
Each batch was compared against a “golden board” baseline, verifying that signal accuracy, impedance, and sensor readings matched within ±1%.
Once the line was validated, we transitioned to high-volume production. Maintaining quality at this stage meant rigorous process control:
Through these methods, we achieved a first-pass yield rate of 99.3% — a level usually reserved for much larger OEM operations.
Each unit underwent:
After shipment, the client conducted third-party verification testing — and found zero measurable performance drift across 10,000 devices.
This project reinforced what we emphasize in every Electronic Manufacturing partnership:
Scaling from prototype to 10K units doesn’t have to mean sacrificing precision. With the right partner, you can maintain medical-grade quality while achieving cost-effective production.
At Fumax, we make that possible through a seamless integration of Electronic Design, PCB Assembly, and Manufacturing Excellence — proven in every unit we deliver.
