Introduction of copper clad laminate
Copper Clad Laminate (Copper Clad Laminate,CCL) is a plate-shaped material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin, covering one or both sides with copper foil and hot pressing, referred to as copper clad laminate. Printed circuit boards of various forms and functions are selectively processed, etched, drilled and copper plated on copper clad laminates to make different printed circuits. The printed circuit board mainly plays the role of interconnection, insulation and support, and has a great influence on the signal transmission speed, energy loss and characteristic impedance in the circuit. Therefore, the performance, quality, and manufacturing of the printed circuit board The processability, manufacturing level, manufacturing cost, and long-term reliability and stability depend to a large extent on the copper clad laminate.
Copper clad laminate manufacturing industry is a sunrise industry, it is accompanied by the development of electronic information, communications industry, has broad prospects for development, its manufacturing technology is a multidisciplinary cross-cutting, mutual penetration, mutual promotion of high-tech. It is inseparable from the development of the electronic information industry, especially the printed circuit industry. Its progress and development has been driven by the innovation and development of electronic products, semiconductor manufacturing technology, electronic installation technology and printed circuit board manufacturing technology.
Generally speaking, copper clad laminate can be divided into two categories: rigid copper clad laminate and flexible copper clad laminate.
1.2.1 Rigid Copper Clad Laminate
22.214.171.124 According to the different insulating materials and structure of copper clad laminate, it can be divided into organic resin copper clad laminate, metal-based (core) copper clad laminate and ceramic-based copper clad laminate.
126.96.36.199 According to the thickness of copper clad laminate, it can be divided into conventional plate and thin plate.
188.8.131.52 According to the reinforced materials used in copper clad laminate, it can be divided into electronic glass fiber cloth-based copper clad laminate, paper-based copper clad laminate and composite-based copper clad laminate.
184.108.40.206 According to the insulation resin used in the copper clad laminate, a certain resin is called a resin copper clad laminate. Such as epoxy resin copper clad laminate, polyester resin copper clad laminate and cyanate resin copper clad laminate and so on.
In addition, there are special rigid copper clad laminates divided according to flame retardant grade and some special properties.
1.2.2 Flexible Copper Clad Laminate
At present, flexible copper clad laminates are divided into three types: polyester film type (flame retardant and non-flame retardant), polyimide film type (flame retardant, non-flame retardant, two-layer method and three-layer method) and extremely thin electronic glass fiber cloth type.
