About This Product

In 1989, we succeeded in commercializing two-layer FCCL (adhesive-free copper clad laminate) for the first time in the world. This is our main product for high-performance flexible printed wiring boards and currently boasts the world's top share. By taking advantage of the properties of polyimide resin created by our unique design and synthesis technology, we are able to support applications that require flexibility, such as high flexibility and fine circuit formation, as well as bending and mounting into narrow housings. This adhesive-free copper clad laminate is uniquely designed by our company for applications that require particular flexibility, such as folding and mounting into narrow frameworks.
