What is CCL?
What is CCL? Many people have such a question. Today, Anneng Electronics will answer this question for you.
Copper Clad Laminate (CCL), also known as copper clad laminate, is the basic material of the electronic industry, mainly used for processing and manufacturing printed circuit boards (PCBs), and is an important material for making PCBs. Copper clad laminate is used in computer, communication equipment, consumer electronics, automotive electronics and other industries through PCB.
PCB, known as the "mother of electronic products", is a printed board that forms point to point connections and printed components on various types of copper clad plates according to the predetermined design. It mainly enables various electronic components to form the predetermined circuit connections. Most electronic equipment must be equipped with PCB to realize multiple functions such as power supply for electronic equipment, digital and analog signal transmission, RF microwave signal transmission and reception.
The CCL industry originated in the 1940s. During the 80 years of development, major manufacturers have accumulated technological advantages, financial advantages, customer resources and other advantages, gradually established the industry access threshold, and the industry concentration has continued to increase. According to the data of Prospective Industry Research Institute, CCL accounts for 30% of PCB cost composition. As the main raw material for PCB manufacturing, the demand of CCL will be driven by the downstream PCB market.
The upstream of PCB industry chain includes copper foil, copper ball, copper clad laminate, semi curing sheet, gold salt and ink, and the overall material cost accounts for nearly 60%. The whole industrial chain chain can be simplified as copper foil → copper clad laminate → PCB → application.
The nature of the industry is both cyclical and growth. The periodicity is reflected in that the outbreak of new demand will drive the basic materials to complete a cycle of "high-speed growth → market peak → demand reduction". The growth is reflected in that the new demand for small and special materials will push up the value level of the whole market, thus increasing the output value of the whole market.
Among the upstream materials, copper clad laminate is mainly responsible for the three functions of PCB: conductivity, insulation and support. Its performance directly determines the performance of PCB. It is the key basic material for PCB production, accounting for 20% - 40% of the direct materials.
