The description of copper-clad laminated board
Copper-clad laminated board is a plate-like material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin which covered with copper foil on one or both sides and hot-pressed. It is called copper-clad laminate board (Copper Clad Laminate (CCL), referred to as copper clad laminate.
Copper-clad laminated board are extremely important basic materials for printed circuit boards. Printed circuit boards in various forms and functions are processed, etched, drilled, and copper plated on copper clad laminates. Different printed circuits (single-sided, double-sided, multilayer).
As a substrate material in the manufacture of printed circuit boards, copper clad laminates board mainly play the role of interconnection, insulation and support for printed circuit boards and have a great influence on the transmission speed, energy loss and characteristic impedance of signals in the circuit. Therefore, the performance, quality, workability in manufacturing, manufacturing level, manufacturing cost, and long-term reliability and stability of printed circuit boards depend to a large extent on copper clad laminates.
The copper-clad laminated board manufacturing industry is a sunrise industry. With the development of electronic information and communication industry which has broad development prospects. Copper-clad laminated board manufacturing technology is a multi-disciplinary interpenetrating, interpenetrating and mutually promoting high-tech. It is inseparable with the electronic information industry, especially with the printed circuit industry. Its progress and development have been driven by the innovation and development of electronic machine products, semiconductor manufacturing technology, electronic mounting technology and printed circuit board manufacturing technology.
The applications of copper-clad laminated board
Traditional copper clad laminates board are mainly used to manufacture printed circuit boards to support, interconnect and insulate electronic components. They are called important basic materials for printed circuit boards. Copper-clad laminated board is an important electronic material that is indispensable for all electronic products, including all electronic products such as aviation, aerospace, remote sensing, telemetry, remote control, communications, computers, industrial controls, household appliances and even advanced children’s toys. With the continuous improvement of technological level, some special electronic copper clad laminates have also been used to directly manufacture printed electronic components in recent years.
Due to the small size, light weight and thinness of electronic products, printed copper-clad laminated board must have various high-quality and high-tech features, so that printed circuit board manufacturing technology directly involves a variety of contemporary high-tech, its main and most important The material of copper-clad laminated board must be accompanied by various high-quality and high-tech characteristics.
Therefore, the position of copper-clad laminated board in the electronic information industry becomes more and more important.
Mainland China has long become a global producer of copper-clad laminated board and is now in a critical period of shifting to a technologically strong country. In recent years, more and more foreign and foreign companies have invested in PCBs, CCLs, materials, and equipment in mainland China. The amount of investment is increasing and the industrial chain is becoming longer and longer. , FPC, IC board and CCL’s growth momentum has not diminished.
