What is a copper clad laminate?

Copper clad laminate (CCL) is a kind of plate-like material which is made by impregnating electronic glass fiber cloth or other reinforcing materials in resin, covering copper foil on one side or both sides, and hot pressing. Printed circuit boards with different shapes and functions are selectively processed, etched, drilled and plated with copper on copper clad laminate to make different printed circuits. It mainly plays the role of interconnection, insulation and support for printed circuit boards, and has a great influence on the transmission speed, energy loss and characteristic impedance of signals in the circuit. Therefore, the performance, quality, manufacturability, manufacturing level, manufacturing cost, long-term reliability and stability of printed circuit board are largely determined by copper clad laminate. Main uses of copper clad laminate: Traditional copper clad laminate (CCL) is mainly used to manufacture printed circuit boards (PCB) to support, interconnect and insulate electronic components. Known as an important basic material of polychlorinated biphenyls. It is an indispensable and important electronic material for all electronic products, including aviation, aerospace, remote sensing, telemetry, remote control, communication, computer, industrial control, household appliances and even advanced children's toys. With the development of science and technology, some special electronic copper clad laminates have been used to directly manufacture printed electronic components in recent years. Because electronic products are small, light and thin, printed circuit boards must have all kinds of high-quality and high-tech characteristics, which makes the manufacturing technology of printed circuit boards directly related to all kinds of modern high-tech. Its main and most important material, copper clad laminate, must also have various high-quality and high-tech characteristics. Therefore, the position of copper clad laminate in electronic information industry is becoming more and more important.
