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

The Dual Layer Flexible PCB from PCBSYNC is engineered to solve complex routing challenges in modern, space-constrained electronics. Featuring a dual-layer copper construction bonded to a premium polyimide base, this flexible circuit allows for reliable dynamic flexing and high-density component placement. Integrated Plated Through Hole (PTH) technology ensures stable electrical conductivity between layers, while the Electroless Nickel Immersion Gold (ENIG) finish provides excellent surface flatness for precise surface-mount component soldering and superior oxidation resistance.

Key Features of our Dual Layer Flexible PCB

  • Layer Count: 2 Layers (Dual-layer double-sided flexible circuit)

  • Base Material: Polyimide (PI) with options for adhesiveless base copper

  • Surface Finish: ENIG (Electroless Nickel Immersion Gold) for enhanced solderability

  • Via Technology: Precision Plated Through Hole (PTH) for reliable interlayer connections

  • Copper Thickness: 0.5 oz to 2 oz depending on current-carrying requirements

  • Min Line Width/Spacing: 0.075 mm / 0.075 mm (3 mil / 3 mil)

  • Stiffener Options: FR4, Polyimide, or Aluminium stiffeners available for component support zones

  • Compliance: RoHS compliant, manufactured to IPC-6013 Class 2/3 standards

Applications

  • Medical Devices: Handheld diagnostics, implantable electronics, and wearable monitoring sensors.

  • Aerospace & Defence: High-vibration avionics instrumentation and satellite communication modules.

  • Automotive Systems: Battery management systems (BMS), sensor clusters, and infotainment wiring harnesses.

  • Consumer Electronics: Smart wearables, folding smartphones, and compact camera modules.
