Doubel side copper clad laminated sheet for CCL pcb material, which is made of wood pulp paper or fiberglass cloth, is immersed in resin, and is coated with copper foil on one or both sides and hot pressed.
FR4 CCL products are directly used as substrate materials in the manufacturing process of printed circuit boards. Printed circuit boards are widely used in computers, communications, consumer electronics, industrial/medical, military, semiconductor and automotive industries, and almost all electronic information products are involved. Among them, computer, communication and consumer electronics are the three main application areas, accounting for about 70% of the output value of the PCB industry; all kinds of insulating materials are directly used in the production of insulating assemblies, and the end customers mainly include electrical and electronic equipment, instruments, computers, Communications, consumer electronics and transportation. After decades of market competition, the CCL industry has formed a relatively concentrated and stable supply pattern. The world's top three market share is about 33.6%, and the top ten market share is about 72.5%.
China's CCL industry has been in existence since the mid-1950s and has a history of more than 50 years. Today, China has become the world's largest producer of Doubel side copper clad laminated sheet for CCL pcb material. These decades are a history of constant innovation, constant pursuit, and rapid development. As a veteran manufacturer of insulating materials, ZTELEC invests a lot of time and money in research and development every year, and finally develops ultra-thin high-frequency copper clad laminates.
