Shenzhen's 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 FPC flexible circuit board in smart phones still faces many technical difficulties, which will become the focus of current manufacturers to overcome.  

FPC 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.  

FPC flexible circuit board is mainly used in mobile terminal.  Consumer electronics. Automotive electronics.  Industrial control. Medical. Aerospace military, etc.  Among them, mobile terminal class is the largest application field of FPC flexible circuit board, especially smart phones, and it is also the field where the technical ability of flexible circuit board is the highest, and it will lead the technical development direction of FPC 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 for FPC 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 middle socket can be extended, and the FPC flexible circuit board can be plugged and inserted with gold fingers to reinforce.  

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.  

FPC flexible circuit board honestly in mobile phone applications will become a set trend, which also makes FPC flexible circuit board market present a positive situation.  However, FPC flexible circuit board is still facing manufacturing problems, such as the application of large size in foldable mobile phones, etc. Of course, there are corresponding solutions to these problems, but these solutions inevitably bring an increase in cost.  How to better control the cost of FPC flexible circuit board, can only rely on mass production or technology upgrade to solve.
