Prototype Assembly

Our prototype runs are often a mix of large BGAs and tiny 0201 components, and we’ve had issues with other assembers on yield. PCBsync’s assembly team delivered a perfect first-run success. The board was pristine, the solder joints were impeccable under the microscope, and everything worked straight out of the box. Their attention to detail in the assembly process saved us weeks of debug time. They are now our go-to for critical prototype assembly.

Electronic Manufacturing

Scaling from hundreds to tens of thousands of units for our smart home device presented huge supply chain and manufacturing challenges. PCBsync’s full electronic manufacturing service was the solution. They didn’t just build the PCB; they managed the entire box-build, sourced all components (even during shortages), and implemented a rigorous quality control system that drastically reduced our field failure rate. They act as a true extension of our own production team.

PCBSync Fitness Tracker Rigid-Flex PCB with ENIG and PI Stiffener

Product Details

Build smarter wearables with precision-engineered Rigid-Flex PCB technology designed for next-generation fitness trackers.

The PCBSync Fitness Tracker Rigid-Flex PCB delivers the perfect balance of flexibility and structural integrity for compact wearable electronics. Engineered with Electroless Nickel Immersion Gold (ENIG) surface finish and Polyimide (PI) Stiffener, this board is built to meet the rigorous demands of modern fitness tracking devices — from heart rate monitors to GPS-enabled smartbands.

Why Choose PCBSync Rigid-Flex PCB?

✅ ENIG Surface Finish for Superior Connectivity

Our ENIG coating provides a flat, oxidation-resistant surface that ensures reliable solderability, excellent contact for fine-pitch components, and long-term signal integrity — critical for the sensitive sensors used in fitness wearables.

✅ Polyimide (PI) Stiffener for Targeted Rigidity

The integrated PI Stiffener reinforces connector zones and component pads without compromising the board’s flexibility. This reduces mechanical stress on solder joints, extending the lifespan of your fitness tracker in high-movement environments.

✅ Rigid-Flex Construction — Space & Weight Saving

By combining rigid and flexible layers in a single PCB, PCBSync eliminates the need for multiple connectors and ribbon cables, resulting in a lighter, thinner, and more compact design — ideal for slim fitness tracker form factors.
