Flexible PCB is a kind of high reliability, which is made of polyimide or polyester film as base material, excellent flexible printed circuit board, with high density, light weight, Flex PCB thin thickness characteristics, mainly used in mobile phones, laptops, PDAs, digital cameras, LCM and many other products. Flexible circuits are usually the only solution for miniaturization and mobility requirements on the current connector (cutting-edge) electronic device assembly board. The total weight and volume of flexible assembly is 70% less than that of traditional round wire wiring harness.
Flexible circuit board with high density, light weight, thin thickness, Flex PCB good bending characteristics, is widely used in mobile phones, computer and LCD screen, CD walkman, disk drive, the latest use and other fields.
Flexible PCB light weight and thin thickness. Flex PCB Can effectively save the volume of products, easy to connect the battery, microphone, and the button into one.
Flexible PCB production process
Open material → drilling →pth→ electroplating → pretreatment → dry film → to the position → exposure → development → graphic plating → off film → pretreatment → dry film → to the position of exposure → development → etching → off film → surface treatment → overlay film → suppression → curing → immersion nickel gold → printing character → shearing → electric test → punching and cutting → final inspection → package Loading → Shipping
Single panel System
Open material → drilling → dry film → to the position → exposure → development → etching → off film → surface treatment → cover film → suppression → curing → surface treatment → immersion nickel gold → printing character → shearing → electrical testing → blanking → final inspection → packaging → shipments
Application and development of flexible PCB
With the change of the Times people's living standards are also changing, electronic technology has become an indispensable part of human life. So people for electronic products also increased. To meet our needs, flexible PCB is an essential part of the small, compact, lightweight, and built-in functional requirements of electronic products. Because it has a very obvious advantage, such as: flexible structure, small size, light weight, Flex PCB and even rotating folding requirements. Based on China is the world's largest population, flexible PCB in China has a very broad economic market, Flex PCB China's flexible circuit board emerging enterprises have a difficult to measure the future of development.
