Copper Clad Laminate, abbreviated to CCL, is a type of base material of PCBs. With glass fiber or wood pulp paper as reinforcing material, a CCL is a type of product through lamination with copper clad on either one side or both sides of reinforcing material after being soaked in resin.
According to different classification standards, CCLs can be classified into various categories:• Based on CCL mechanical rigidity, we have rigid CCL(FR-4, CEM-1, etc.) and flex CCL. Rigid PCBs depend on rigid CCLs while
flex PCBs are on flex CCLs (flex-rigid PCBs are on both rigid CCLs and flex CCLs).
• Based on insulation material and structures, we have organic resin CCL (FR-4, CEM-3, etc.), metal-base CCL, ceramic-base CCL etc.
• Based on CCL thickness, we have standard thickness CCL and thin CCL. The former one requires at least 0.5mm thickness while
the latter can be thinner than 0.5mm. Copper foil thickness is excluded from CCL thickness.
• Based on reinforcing material types, we have glass fiber cloth base CCL (FR-4, FR-5), paper base CCL (XPC), compound CCL
(CEM-1, CEM-3).
• Based on applied insulation resin, we have epoxy resin CCL (FR-4, CEM-3) and Phenolic CCL (FR-1, XPC).
Classification:
1. According to the mechanical rigidity of CCL, it is divided into rigid CCL and flexible CCL;
2. According to the insulating material and structure of CCL, it is divided into organic resin CCL, metal-based CCL, and ceramic-based CCL;
3. According to the thickness of the copper clad laminate, it is divided into thick plate (the thickness range is 0.8~3.2mm (including Cu)), thin plate (the thickness range is less than 0.78mm (excluding Cu));
4. According to the reinforcing material of CCL, it is divided into glass cloth base CCL, paper base CCL and composite base CCL (CME-1, CME-2).
5. According to the flame retardant grade, it is divided into flame retardant board and non-flame retardant board.
6. According to some properties of CCL, it is divided into high Tg board (Tg≥170ºC), high dielectric performance board, high CTI board (CTI≥600V), environmentally friendly CCL (halogen-free, antimony-free), ultraviolet light Shielded CCL.

Features: XPC Copper clad laminated sheet/CCL consist of bleached wood pulp paper, impregnated with modified phenolic resin and clad with electrolytic copper foil.It has high dimension stability, good punching behavior at low temperature, high thermal resistance and are widely used for computers, telephones, Hi-Fi acoustic devices, electronic toys and etc.
Note:Different thickness copper foil in one side or double sides can be supplied. 18um,25um,35um,70umCopper clad laminate sheet ( the full name of copper clad laminate, CCL for short), is made of wood pulp paper or glass fiber cloth as a reinforcing material, impregnated with resin, and covered with copper foil on one or both sides. into a product. CCL is the basic material of the electronics industry, mainly used for processing and manufacturing printed circuit boards (PCB), widely used in televisions, radios, computers, computers, mobile communications and other electronic products. The copper clad laminate industry has a history of nearly 100 years. The development of CCL began in the early 20th century. At that time, there was a gratifying progress in the manufacture of resins, reinforcing materials and substrates for copper clad laminates.
