The services common sense of the flexible printed circuit board

By tingyuya

??The services common sense of the flexible printed circuit board
??The flexible PCBs & Manufacturing Services (Flexible Printed Circuit Board) is a printed circuit, made of a flexible insulating substrate having not have the advantages of many of the rigid printed circuit board. For example, it can be freely bent, winding, folding, require any arrangements in accordance with the spatial layout, and move freely in three-dimensional space and telescopic, so as to achieve the integration of the components assembly and wire connections. Using FPC can be greatly reduced the volume of the electronic products, applicable to electronic products to high density, the miniaturization, high reliability direction needs. Therefore, FPC has been widely applied in the field of aerospace, military, mobile communications, portable computers, computer peripherals, PDAs, digital cameras or product. FPC also has good heat resistance and weldability and ease of loading even lower comprehensive cost advantages, Rigid-Flex design also to some extent make up for lack of the flexible substrate component carrying capacity slightly.
??The single-sided, double-sided and multilayer flexible printed circuit boards. The substrate used mainly polyimide CCL. Such materials have high heat resistance, good dimensional stability, by pressing with both mechanical protection and good electrical insulation properties of the covering film made of the final product. Electrical connection of double-sided, the surface layer and the inner layer of the multilayer printed wiring board conductor through metalization to achieve the inner and outer layer circuit. Batteries & Power Supplies
??The name of the parameter values of the printed circuit board service indicators
??Substrate thickness (?m) of polyimide 25,35,50
??Polyester 25, 50, 75, 100
??The thickness of the copper conductor (?m) 18,35,50,70,105
??The minimum line width (mm) 0.1/0.1
??The smallest aperture (mm) 0.3
??The largest monolithic product size (mm × mm) 350 × 350
??Peel strength (n / mm) 1.0
??Insulation resistance (M?)> 500
??Dielectric strength (V / mm)> 1000
??To resistance welding polyimide 260 ? 10 seconds
??Polyester 243 ? 5 seconds
