Shenzhen Liansheng Electronic Industry Co., Ltd

Engineered specifically for Human-Machine Interface (HMI) applications, our double-sided Flexible Printed Circuit (FPC) is the premier choice for modern membrane switches and keypads. Manufactured on a durable polyimide (PI) substrate with a premium ENIG (Electroless Nickel Immersion Gold) surface finish, this FPC ensures superior conductivity, oxidation resistance, and exceptional wear characteristics for millions of actuations. This high-reliability construction guarantees consistent tactile performance and longevity, making it ideal for critical applications in industrial control panels, medical devices, and high-use consumer electronics.

The inherent advantages of our flexible PCB technology allow for significant product design and assembly benefits. Its thin, lightweight, and pliable nature enables sleeker, more ergonomic, and even curved HMI designs that are impossible with rigid boards. This FPC integrates the entire circuit schematic into a single part, eliminating the need for complex wire harnesses and connectors, which dramatically simplifies the assembly process, reduces labor costs, and minimizes potential points of failure. With excellent resistance to vibration, high temperatures, and chemical exposure, our FPC for membrane switches provides a robust and cost-effective solution built to perform reliably in the most demanding environments.
