The flexible board (Flexible Printed Circuit Board) is also called "FPC flexible plate",it is made of insulation materials ,rigid printed circuit board has many advantages compared with. For example, it can be bent freely, winding and folding,it can be arranged in accordance with the requirements of any space layout, and moving in arbitrary dimensional space and expansion,so as to achieve the integration of component assembly and wire connection.The use of FPC flexible board can greatly reduce the volume of electronic products,the need for the development of electronic products with high density, miniaturization, high reliability direction. Therefore, FPC flexible board has been widely used in aerospace, military, mobile communications, computer, computer peripherals, PDA, digital cameras and other field or product.
FPC flexible board also has good heat resistance and solderability and it is easy to assembly,it integrated the advantages of lower cost,a combination of hardware and software design also in a certain extent can make up the flexible substrate in element bearing capacity of slightly. Flexible printed circuit board with single-sided, double-sided and multilayer board of. The substrate is used in copper-clad polyimide based. This material has high heat resistance, good dimensional stability, and the final product film and both mechanical protection and good electrical insulation properties by pressing. Double-sided, multilayer printed circuit board surface and the inner conductor by metal electrical circuit connecting the inner and outer layer.
FPC flexible board type
1, a single panel with a single PI copper clad plate materials on the line, then it covered with a layer of protective film, flexible board can only form a single conductor.
2, ordinary double sided board use double PI plate laminate materials in double-sided circuit, both with a layer of protective film,a circuit board with double conductor.
3, the substrate generated single panel using pure copper material in circuit fabrication, respectively
4, the substrate generated double sided board using two layers of single PI copper-clad laminate materials supplemented ,local separation of two level structure of double conductor circuit board to achieve in the delamination area with high flexural performance of circuit board
