The flexible copper clad laminate sheets (CCL) is a plate-shaped insulation material made of copper foil on one or two sides and pressed by thermal pressure, simply called copper plate, immersed in resin, one or both sides. Printed circuit boards in different forms and functions are selected for processing, etching, drilling and copper plating on copper-coated plates to make different printing circuits. The printing circuit board mainly acts as interconnecting on, insulation and support, and has a great influence on the transmission speed, energy loss and characteristic impedance of signals in the circuit, so the performance, quality, processing in manufacturing, manufacturing level, manufacturing cost and long-term reliability and stability of the printed circuit board depend to a large extent on the flexible copper clad laminate sheets.

The flexible copper clad laminate sheets classification:

A, The mechanical rigidity of the flexible copper clad laminate sheets is divided into rigid copper plate and flexible copper plate;

B, According to the insulation material of flexible copper clad laminate sheets, the structure is divided into organic resin-coated copper plate, metal-based copper plate, ceramic-based copper plate;

C, According to the thickness of the flexible copper clad laminate sheets is divided into thick plate (thickness range of 0.8 to 3.2mm (including Cu),) sheet (thickness range is less than 0.78mm (excluding Cu);

D, The reinforced material by flexible copper clad laminate sheets is divided into glass cloth-based copper plate, paper-based copper plate, composite base copper plate (CME-1, CME-2).

E,Divided into flame retardant flexible copper clad laminate sheets and non-flame retardant plates according to flame retardant grade.

F, According to the flexible copper clad laminate sheets of certain properties divided into high Tg plate (Tg s 170 degrees C), high dielectric performance plate, high CTI plate (CTI s 600V), environmental protection copper plate (no halogen, no palladium), uv-masked copper plate.
