Why Flexible PCBs Matter
Traditional rigid boards can't cope with repeated bending or the dynamic movement required in a foldable phone. Flexible PCBs, however, are made from bendable materials like polyimide, which allow them to endure constant folding without cracking or breaking. They serve as the vital wiring system connecting various parts of the phone—screens, batteries, processors—through the hinge.
Key Benefits in Foldable Designs
Bendability & DurabilityFlexible PCBs can bend tens of thousands of times without fatigue, making them ideal for devices that fold and unfold daily.
Space-Saving LayoutsTheir slim, lightweight structure allows designers to use internal space more efficiently—key for foldables, where space is extremely limited.
Fewer ConnectorsFlex PCBs reduce the number of connectors required, simplifying assembly and minimizing potential failure points.
Signal IntegrityWith proper design, flex boards maintain strong signal transmission even during motion, ensuring consistent performance.
How SUNSOAR Supports Next-Gen Devices
At SUNSOAR, we manufacture high-reliability flex and rigid-flex PCBs tailored for foldable applications. From controlled impedance for high-speed data to ultra-thin copper layers and tight bend radius tolerances, we engineer each board to meet demanding mechanical and electrical specs.
We also assist clients from early design to prototyping and mass production—offering full DFM (Design for Manufacturability) support and quick-turn services for R&D teams in need of speed and flexibility.
Foldable smartphones represent the future of mobile design—and flexible PCBs are what make that future possible. As the market grows, so will the demand for high-performance flex circuits. SUNSOAR is proud to be at the forefront of that transformation.
