These are flexible circuit boards (FPCs) on several modules Board layer: double-sided board Line width: 0.06mm Line spacing: 0.06mm Aperture: 0.2mm Color: Yellow Product Introduction It is a printed circuit board made of flexible copper-clad laminates as the substrate, used as a signal transmission medium for electronic product connections. It is generally composed of a conductive layer (such as copper foil), a substrate layer (flexible polyester film or polyimide film), and a protective layer. The conductive layer realizes electrical connection, the base layer provides support and insulation, and the protective layer prevents damage to the conductive layer and the base layer. It can be divided into single-layer, double-layer, multi-layer, and soft hard combination versions, which can be customized according to different application scenarios and performance requirements. Product advantages -High flexibility: It has excellent flexibility and bendability, and can be bent, folded, and twisted according to the internal space form of devices such as cars, mobile phones, computers, tablets, and industrial capacitive screens, adapting to complex assembly environments and achieving efficient layout in compact spaces. -Lightweight and portable: Made of flexible materials with thin thickness and light weight, it is conducive to the design of devices that are lightweight, compact, and lightweight. Reducing space occupation and weight in mobile phones; In cars, it can help reduce the weight of the entire vehicle, improve range and handling performance. -Excellent electrical performance: can achieve high-density wiring, increase connection interfaces, and meet the high integration requirements of equipment; Stable signal transmission can effectively reduce electromagnetic interference and ensure stable operation of equipment. -Good environmental adaptability: It has good resistance to high temperature, humidity, vibration, and impact, and can work stably in harsh environmental conditions, meeting the requirements of automotive and other application scenarios. -Design and manufacturing advantages: It can achieve diversified design and meet the customized needs of different customers; The production process is mature, and some processes can be automated, which can improve production efficiency and reduce costs.
