Upgrade your electronics design with the PCBSync 4-Layer Rigid-Flex PCB, engineered for applications demanding both mechanical flexibility and structural integrity. Combining advanced rigid-flex technology with a polyimide stiffener and ENIG (Electroless Nickel Immersion Gold) surface finish, this PCB delivers unmatched reliability in compact, high-performance devices.
What Is a 4-Layer Rigid-Flex PCB?
A 4-layer rigid-flex PCB integrates flexible polyimide substrates with rigid board sections into a single, unified circuit. This design eliminates traditional wire harnesses and connectors, reducing assembly complexity, minimizing failure points, and saving valuable space — ideal for aerospace, medical devices, wearables, and consumer electronics.
Key Features & Benefits
- 4-Layer Construction – Supports complex signal routing, power planes, and ground planes within a slim profile, enabling high-density interconnects without sacrificing performance.
- Polyimide Stiffener – Reinforces flex zones at connector and component mounting areas, preventing mechanical stress and ensuring long-term durability during repeated bending cycles.
- ENIG Surface Finish – The electroless nickel immersion gold coating provides superior solderability, a flat pad surface for fine-pitch SMT components, and excellent corrosion resistance for extended product lifespan.
- High Reliability – Manufactured to IPC-6013 standards, PCBSync rigid-flex boards undergo rigorous quality control to meet demanding industry certifications.
Applications
The PCBSync 4-Layer Rigid-Flex PCB with Polyimide Stiffener and ENIG is widely used in medical wearables, military electronics, IoT devices, robotics, and smartphone components — anywhere space savings and signal integrity are critical.
