         As the introduction rate of rigid-flex boards in electronic products is getting higher and higher, the importance of PCB industry continues to increase. In the past, rigid-flex boards were mostly used in the field of mobile phone batteries, and the market has gradually become popular among PCB companies such as Huatong and Xinxing. However, after the emergence of new applications such as lens modules, display modules, true wireless Bluetooth headsets, and wearable devices, more and more manufacturers are willing to invest. In addition to Taiwan’s small and medium-sized enterprises Yaohua and Dingying, the leading players Factory Zhending and many mainland Chinese manufacturers have begun to deploy.
      1. What is a rigid-flex board?

      The birth and development of FPC and PCB gave birth to the new product of soft and hard board. Therefore, the rigid-flex board is the flexible circuit board and the rigid circuit board, which are combined together according to relevant process requirements through pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics.

     2. Classification of soft and hard board:

     If it is classified according to the manufacturing process, the method of joining the soft board and the hard board can be divided into two types of products: the soft-hard composite board and the soft-hard composite board. The difference lies in the technology of the soft-hard composite board. The soft board and the hard board can be Combination, among them, there are common blind hole and buried hole design, so higher density circuit design is possible, and the technology of flexible and hard board is to separate the soft and hard boards and then press them into a single circuit board. , There is a signal connection but no through hole design. But at present, the commonly used "rigid-flex board" collectively refers to all rigid-flex board products without subdividing the two.
    Rigid and flexible boards were first used in the field of battery modules. Now looking at all mobile phone brands in the world, it is a consensus to use rigid and flexible boards for batteries, and it may become a long-term trend. At the same time, in order to accommodate more lenses in a smaller and smaller space, mobile phone lens modules have also begun to use soft and hard combination boards. Currently, Korean and Chinese brand mobile phones use soft and hard combination boards as the mainstream lens technology. It has also gradually expanded to other mobile phone modules such as displays. As for the characteristics of lightweight and multi-functional wearable devices, it is naturally expected to become the next application for the large-scale introduction of rigid-flex boards.

  In the future, the chances of seeing a combination of soft and hard boards in other consumer electronics products will only increase. Some industry players have revealed that the IoT products they see now, including smart speakers and other smart home appliances, may be due to their design and For cost requirements, a combination of soft and hard boards is used in specific functional modules.
