Soft board FPC common sense

   Flexible board (FPC) Circuit (Flexible Printed Board) is a flexible insulating substrate printed circuit, with many rigid printed circuit board does not have the advantages. For example, it is free to bend, winding, folding, according to the requirements of the spatial layout of any arrangement, and in the three-dimensional space of arbitrary movement and expansion, so as to achieve the integration of the assembly and wire connection. The use of FPC can greatly reduce the volume of electronic products, electronic products to high density, miniaturization, high reliability direction. Therefore, FPC has been widely used in the fields of aerospace, military, mobile communication, portable computers, computer peripherals, PDA, digital cameras and other products.
    FPC also has good heat resistance and weldability, easy installation and low cost advantages, even integrated design, hardware and software combination also make up the flexible substrate in the element bearing the limitations slightly in a certain extent. Flexible printed circuit board has one side, two sided and multilayer board. The base material is mainly made of polyimide copper clad laminate. The material has high heat resistance, good dimensional stability, and has a mechanical protection and good electrical insulation properties of the covering film by pressing into the final product. The surface and inner conductor of the double side and multilayer printed circuit board are electrically connected with the inner and outer layers. Index name parameter values of substrate thickness (m) of 35, 50 PI 25, 50, 25 polyester, 75100 copper conductor thickness (m) of 18, 35, 50, 70105 the minimum line width from (mm) 0.1/0.1 (mm) 0.3 maximum minimum aperture single product size (mm * mm) 350 x 350 peel the intensity of (n/mm) 1 (M) insulation resistance dielectric strength (V/mm) > 500 > 1000 resistance welding polyimide 260 C 243 C 5 seconds and 10 seconds of polyester
