Laminated Copper Clad Laminate (LCCL) is one of the key materials for manufacturing copper-clad circuit boards. It is composed of one or more layers of copper foil and non-conductive substrate through lamination process, with excellent electrical performance and mechanical strength, and is widely used in the production of various electronic devices.

　　The main components of copper-clad laminates include copper foil and substrate. Copper foil is usually made of high-purity electrolytic copper, with a thickness ranging from a few micrometers to several hundred micrometers, and suitable specifications can be selected according to needs. The substrate is usually made of fiberglass cloth impregnated with epoxy resin or other synthetic resins, which are then hot pressed and cured to form a hard composite material. This structure not only provides good conductivity and thermal conductivity, but also has high heat and chemical resistance.

　　In the manufacturing process, copper clad laminates require multiple processes, including cutting, drilling, copper plating, etching, and lamination. Firstly, cut and drill the substrate and copper foil according to the design requirements, and then perform copper plating treatment on the surface of the copper foil to enhance conductivity and corrosion resistance. Next, the unwanted copper foil is removed through an etching process to form a circuit pattern. Finally, multiple layers are combined together through a lamination process to form a multi-layer copper clad laminate.

　　The application range of copper-clad laminates is very wide. In the field of electronic communication, it is used to manufacture high-frequency circuit boards to meet the high bandwidth and low latency requirements of 5G communication. In the field of automotive electronics, copper clad laminate is used to manufacture key components such as vehicle navigation system, auto drive system and electric vehicle power management system. In the aerospace field, copper clad laminates need to have higher reliability and environmental adaptability to cope with extreme temperature and pressure changes.

　　In short, as an important basic material in the electronic industry, the quality and performance of copper-clad laminates directly affect the overall performance and service life of electronic equipment. With the advancement of technology and changes in market demand, technological innovation and application expansion of copper-clad laminates will continue to drive the development of the electronic industry.

　　Copper circuit board and copper printed circuit board actually refer to the same electronic component, namely Printed Circuit Board (PCB). In the PCB industry, copper is one of the main materials used to make circuit boards because it has good conductivity and thermal conductivity.
