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.

Product Details

PCBSync HDI Rigid-Flex PCB with Buried Vias and ENIG

Achieve next-level circuit performance with the PCBSync HDI Rigid-Flex PCB with Buried Vias and ENIG finish — engineered for high-density interconnect applications that demand precision, reliability, and compact design.

What Is the PCBSync HDI Rigid-Flex PCB?

The PCBSync HDI Rigid-Flex PCB combines the mechanical durability of rigid boards with the space-saving flexibility of flex circuits. Featuring buried vias and an Electroless Nickel Immersion Gold (ENIG) surface finish, this board is purpose-built for advanced electronics in aerospace, medical devices, wearables, and industrial automation.

Key Features & Benefits

  • HDI Technology – High-Density Interconnect design supports fine-pitch components and complex multilayer routing for miniaturized assemblies.
  • Buried Vias – Internal vias maximize routing space on outer layers, enabling higher circuit density without increasing board size.
  • ENIG Surface Finish – Provides a flat, oxidation-resistant, solderable surface for superior SMT assembly performance and long-term reliability.
  • Rigid-Flex Construction – Eliminates connectors and cables, reducing failure points and overall system weight.
  • Tight Tolerance Manufacturing – Meets IPC-6013 Class 3 standards for mission-critical applications.
  • Customizable Layer Stack-Up – Available in 4 to 20+ layers tailored to your design specifications.

Why Choose PCBSync?

PCBSync delivers certified HDI rigid-flex PCBs with fast turnaround, DFM (Design for Manufacturability) review, and full traceability. Whether you’re prototyping or scaling to production, our engineering team ensures your board performs exactly as designed.
