Achieve unmatched reliability and precision with the PCBSync 6-Layer Rigid-Flex PCB, engineered for demanding electronics applications that require both flexibility and structural integrity. Combining a rigid-flex design with an FR4 stiffener and hard gold surface finish, this board delivers superior performance in aerospace, medical devices, wearables, and high-density consumer electronics.
Why Choose PCBSync Rigid-Flex PCB?
Our 6-layer rigid-flex PCB construction allows seamless integration of flexible circuits and rigid board sections into a single, compact unit — eliminating connectors, reducing assembly errors, and saving valuable space. The FR4 stiffener reinforces critical areas such as connector zones and component pads, preventing mechanical stress and extending board longevity in high-vibration environments.
The hard gold (electroplated gold) surface finish ensures low contact resistance and exceptional wear resistance, making it ideal for edge connectors, gold fingers, and sliding contact applications. Unlike ENIG, hard gold withstands thousands of mating cycles without degradation — perfect for high-reliability connector interfaces.
Key Features:
- 6-layer rigid-flex stackup for complex routing in compact form factors
- FR4 stiffener for mechanical reinforcement at flex-to-rigid transitions
- Hard gold surface finish for durable, corrosion-resistant contact points
- IPC Class 2 / Class 3 manufacturing standards available
- Tight impedance control and fine-pitch capability
- UL-certified materials with RoHS compliance
Ideal Applications: Military electronics, handheld medical devices, wearable tech, RF modules, and industrial control systems.
