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 RO4700 4-Layer RF Board is a high-performance PCB solution specifically designed for the demanding requirements of wearable health monitors and biometric sensing devices. Utilising Rogers RO4700 series thermoset laminates, this board offers the low dielectric loss and thermal stability essential for maintaining signal accuracy in compact, battery-powered devices. Its ultra-slim 0.5mm thickness ensures the flexibility and lightweight form factor required for modern wearable technology.

Key Features

  • Substrate Material: Rogers RO4700 High-Frequency Laminate for superior RF performance.

  • Layer Count: 4-layer stackup optimised for controlled impedance and EMI shielding.

  • Board Thickness: 0.5mm ultra-thin profile for space-constrained wearable housings.

  • Copper Weight: 1oz finished copper for balanced thermal management and conductivity.

  • Surface Finish: 3u Hard Gold (Electrolytic Gold) for enhanced wear resistance and reliable wire bonding or contact points.

  • Solder Mask: High-resolution green (custom colours available) with precise alignment for fine-pitch components.

  • Reliability: Low Z-axis coefficient of thermal expansion (CTE) for increased plated through-hole reliability.

Applications

The unique properties of the RO4700 4-Layer RF Board make it suitable for a variety of high-stakes industries, including:

  • Medical Wearables: Continuous glucose monitors, ECG patches, and pulse oximeters.

  • Wireless Communication: Low-power wide-area networks (LPWAN) and Bluetooth Low Energy (BLE) modules.

  • Fitness Tracking: Advanced smartwatches and performance-monitoring wearables.

  • Internet of Things (IoT): Compact RF sensors for smart home and industrial monitoring.
