Electronic Components Sourcing

Sourcing high-quality electronic components is essential to create quality products for your brand. Choosing the right parts ensures that your products are functional and useful for end users.

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.

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.

Flex-Rigid Hybrid PCB – ENIG + Selective Hard Gold Combination Finish

Product Details

The PCBSYNC Flex-Rigid Hybrid PCB with a combined ENIG and selective hard gold finish provides advanced interconnectivity for complex, space-constrained electronic systems. This specialised board integrates the structural stability of standard FR4 rigid layers with the dynamic bendability of polyimide flexible circuits. By deploying an Electroless Nickel Immersion Gold (ENIG) finish across standard component pads, the board ensures exceptional surface flatness for fine-pitch SMT component placement. Concurrently, a selective hard gold plating is applied to insertion fingers and high-wear contact points, ensuring long-term mechanical durability and minimal contact resistance across multiple mating cycles.

Key Features of the Flex-Rigid Hybrid PCB

  • Dual Surface Finish: ENIG ($3\text{–}5\ \mu\text{in}$ Au over $100\text{–}150\ \mu\text{in}$ Ni) for flawless soldering, combined with Selective Hard Gold ($\ge 30\ \mu\text{in}$ Au over Ni) for robust wear resistance.

  • Layer Count Options: From 4-layer to 20-layer hybrid configurations.

  • Base Materials: High- $T_g$ FR4 combined with polyimide (PI) adhesive-less core layers.

  • Controlled Impedance: Tolerances maintained within $\pm 10\%$ for high-speed signal integrity.

  • Manufacturing Standards: Fully compliant with IPC-A-600 and IPC-6013 Class 2 and Class 3 specifications.

Applications

  • Aerospace & Defence: Mission-critical avionics, flight control systems, and compact telemetry modules.

  • Medical Devices: Multi-axis robotic surgical equipment, internal imaging sensors, and patient monitoring wearables.

  • Industrial Automation: High-vibration robotic joints, multi-planar control units, and sensor arrays.

  • Automotive Electronics: Advanced Driver Assistance Systems (ADAS), radar modules, and compact engine control units.
