Elevate your electronics design with the PCBSync Rigid-Flex PCB featuring an Electroless Soft Gold (Soft ENIG) finish — the premium solution for engineers demanding both mechanical versatility and exceptional surface quality in a single board.
What Is a Rigid-Flex PCB?
A rigid-flex printed circuit board combines rigid FR4 substrates with flexible polyimide layers, enabling three-dimensional routing in compact enclosures. This hybrid construction eliminates the need for connectors and cables, reducing assembly time, minimizing failure points, and shrinking your overall device footprint — ideal for wearables, medical devices, aerospace systems, and industrial IoT applications.
Why Electroless Soft Gold Finish?
Our electroless soft gold surface finish delivers a ultra-thin, pure gold layer over nickel, providing:
- ✅ Excellent solderability for fine-pitch SMT components
- ✅ Wire bondable surface compatible with gold and aluminum bonding
- ✅ Superior corrosion and oxidation resistance for long-term reliability
- ✅ Flat, uniform surface ideal for high-density interconnect (HDI) designs
- ✅ RoHS-compliant and halogen-free construction
PCBSync Quality You Can Count On
Every PCBSync rigid-flex board undergoes 100% electrical testing, AOI inspection, and IPC Class 2/3 compliance checks before shipment. We support layer counts from 2 to 20+, custom impedance control, blind/buried vias, and rapid prototyping turnaround.
Applications: Consumer electronics, RF modules, camera modules, military electronics, automotive sensors.
