Atomfair 3-Layer & Multi-Layer Flexible Copper Clad Laminate (3L FCCL) – International Product Specification

Product Overview

Atomfair 3-Layer and Multi-Layer Flexible Copper Clad Laminate (3L FCCL) utilizes high-performance polyimide (PI) film as the base material. It integrates core advantages of thinness, light weight, and flexibility, while delivering exceptional electrical performance, thermal conductivity, and high-temperature resistance. Its low dielectric constant (DK) enables high-speed electrical signal transmission, superior thermal performance ensures efficient component heat dissipation, and high glass transition temperature (Tg) guarantees stable operation in high-temperature environments.

Supplied in continuous roll form, the product supports automated continuous production of Flexible Printed Circuit Boards (FPCs) and continuous surface mounting of components, significantly boosting manufacturing efficiency and reducing production costs for global customers.
