Foshan foldable phones will be a test case for the industry

Foldable phones have been seen as an industry direction this year with Huawei. Samsung, Royole and others have officially released foldable phones, xiaomi. OPPO. Vivo and other manufacturers have also come up with prototypes of foldable phones. The folding phone has been turned on. The flexible circuit board is light by virtue of its weight. Thin thickness, good bending and other characteristics, become the folding hand machine indispensable components. The application of flexible circuit board in smart phones is still facing many technical difficulties, which will become the focus of the current manufacturers need to overcome.

Flexible circuit board with thin. Bendable. Winding. Foldable. The characteristics of high wiring density, perfect fit the thinness. Miniaturization of the development theme, in recent years to become PCB (printed circuit board) subdivision industry leader. Some experts say that at present in the flexible circuit board, the realization of flexible screen is not difficult, mainly lies in the display screen and PCB hard board, to achieve the folding type PCB also needs a long process of research and development, for electronic materials are also very challenging.

Flexible circuit boards are mainly used in mobile terminals. Consumer electronics. Automotive electronics. Industrial control. Medical. Aerospace military, etc. Among them, mobile terminal class is the largest application field of flexible CIRCUIT board, especially smart phones. It is also the field of the highest technical ability of flexible circuit board, and will lead the technical development direction of flexible circuit board in the future. Miniaturization. Intelligent development trend will promote flexible mobile phones as a trend in the future.

On folding, connection and multiple folding screen to flexible circuit board requirements, experts also put forward solutions. In mobile phones with flexible screens, due to the need to fold for many times and a large number of times, the requirements for flexible circuit boards inside mobile phones will be higher, and the corresponding use area will be further increased. But the flexible circuit board is usually manufactured by intermittent process, so it is limited by the size of the production equipment. In view of this problem, experts believe that the flexible circuit board can be extended through the middle socket, and the flexible circuit board can be reinforced by pulling and inserting gold fingers.

At present, aiming at the connection between soft plate and hard plate, the main process and technology is to make soft and hard plate. Regarding the size problem, the soft plate or soft and hard plate in the industry all use 250MM wide material, and also try to use 500MM wide material.

The increase in the number of applications of flexible circuit board in mobile phones will become a established trend, which also makes the flexible circuit board market present a positive situation. The FPC still faces manufacturing problems, such as large applications on foldable phones. There are solutions to these problems, but they inevitably cost more. How to better control the cost of flexible circuit board, can only rely on mass production or technology upgrade to solve.
