Single Sided Reelable Rigid Flex Circuit Boards (Polyimide PCB, Yellow Soft Board)
These are single‑sided rigid‑flex printed circuit boards constructed with high-performance polyimide (PI) base material, featuring a yellow soft board appearance and designed for reel-to-reel processing. They integrate rigid and flexible regions to support 3D wiring, dynamic bending, folding and miniaturized assembly. Ideal for compact electronic devices, wearable products, connectors, sensors and precision modules requiring high reliability, flex fatigue resistance and automated reel production.
