The birth and development of FPC and PCB gave birth to a new product of rigid-flex PCB. A Rigid-flex board is a circuit board with FPC characteristics and PCB characteristics that are combined with rigid circuit boards after pressing and other processes and according to relevant process requirements. So, what are the applications and development prospects of the rigid-flex board?
The rigid-flex board combines the stability of the rigid board and the flexible board can be assembled three-dimensionally, and its development prospects are very promising. In 2019, the global market size of rigid-flex PCB is about 1.66 billion U.S. dollars, accounting for only about 2.8% of the total; but including smartphones, wireless headsets, drones, cars, AR/VR devices, etc., all have the highest growth rate in 2019 Products, and with more and more follow-up applications, the rigid-flex board is still the product with the most growth momentum in 2020. It is estimated that in 2022, the global market value of rigid-flex boards will reach nearly 2.3 billion U.S. dollars, accounting for about 3.3% of the global circuit board output value.
Mobile device applications are the largest rigid-flex board market in 2019, accounting for about 43% of the overall rigid-flex board market. Applications including smartphone camera lenses, screen signal connections, battery modules, and other applications have significant demand for rigid-flex boards Promote. Especially in the application of smartphone camera lenses, since multi-lens mobile phones have become the design trend of various mobile phone brands, whether it is the increase in the demand for soft and hard boards or the increase in average unit price, it will increase the market share of mobile device applications. proportion.
The development of the mobile phone lens flexible board is mainly due to the lighter, thinner, and high-density requirements of the mobile phone lens, which need to be applied to the rigid-flex board. In addition, based on many factors such as placement, orientation, signal interference, heat dissipation, and specification settings, and some lenses are designed with a periscope structure due to the needs of optical zoom, mobile phone lenses can cope with increasingly stringent space constraints. , From the appearance, there are many different types, and the technical requirements for the rigid-flex board are more stringent, and its application range is wider.
