Flexible PCB Overview
We specialize in custom manufacturing of flexible printed circuit boards (FPC), using high-performance polyimide (PI) and polyester (PET) flexible substrates, covering 1 to 8 layers of designs from rapid prototyping to volume production. Our flexible PCBs feature excellent bending performance, ultra-thin thickness, light weight and three-dimensional wiring capability, can be freely bent, folded and twisted, and maintain stable electrical performance after tens of thousands of bending cycles. Strictly manufactured in accordance with IPC international standards, they are the ideal solution for miniaturized, lightweight and dynamic bending electronic designs, widely used in wearable devices, medical equipment, automotive electronics and other fields.
