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.

Selective Hard Gold FPC – ENIG Base + Hard Gold Connector Zone

Product Details

The Selective Hard Gold FPC provides a dual-surface finish solution for advanced electronic assemblies. By integrating an Electroless Nickel Immersion Gold (ENIG) base with selective hard gold plating on the connector fingers, this Flexible PCB delivers reliable solderability alongside superior wear resistance. Engineers and product developers specify this design for dynamic interconnects that undergo frequent insertion and extraction, preventing oxidation while maintaining consistent conductivity over a prolonged lifecycle.

Key Features of the Selective Hard Gold FPC

Dual Surface Finish: ENIG applied to component pads for flat surface co-planarity and reliable wire bonding, paired with hard gold plating on contact zones.
High-Durability Contacts: Electroplated hard gold (typically 30µ” to 50µ” thickness) provides maximum abrasion resistance for high-cycle mechanical mating.
Advanced Base Material: Built on a polyimide (PI) substrate offering exceptional thermal stability, chemical resistance, and dielectric strength.
Dynamic Flex Endurance: Engineered to withstand tight spatial routing and repeated mechanical bending without trace fracturing or signal degradation.
Compliance & Reliability: Manufactured to strict IPC-6013 standards and fully RoHS compliant.

Applications

Aerospace instrumentation requiring vibration-resistant and highly reliable interconnects.
Medical diagnostic equipment and devices subject to repeated sensor or module swapping.
Industrial automation and robotics control systems operating in harsh environments.
Automotive advanced driver-assistance systems (ADAS) and dense dashboard electronics.
High-end computing peripherals and detachable consumer electronics.
