According to the difference between one covered copper foil or two covered copper foil is called single-sided copper clad plate and double-sided copper clad plate; According to the difference between the copper foil and the substrate film there is no adhesive called the laminated copper plate, no laminated copper plate.
Polyimide (PI), polyester (PET), polyethylene 2,6 naphthalene dicarboxylate (PEN:), liquid crystal polymer (LCP) and other polymer films are commonly used in the substrate film of flexible copper clad plates. Copper clad plate in the whole printed circuit board, mainly responsible for conducting, insulation and support three aspects of the function.
The performance, quality, processability, manufacturing cost and manufacturing level of printed circuit board depend on the performance of copper clad plate to a great extent.
