What is soft and hard combined(rigid-flex) PCB circuit board

Rigid-Flexible PCB: refers to a special circuit board made by laminating a rigid circuit board (PCB) and a flexible circuit board (FPC). The board materials used are mainly rigid board FR4 and flexible board polyimide (PI). The rigid-flex board combines the rigid characteristics of the rigid circuit board with the advantages of the flexible characteristics of the flexible board, so that the PCB is no longer a two-dimensional plane layer of oil, but a three-dimensional internal wiring and arbitrary bending and folding. It can replace a composite printed circuit board connected by multiple connectors, multiple cables and ribbon cables, and has the advantages of making the product stronger, more stable, lighter, and smaller.

What is the purpose of the rigid-flex board?

What is the use of soft and hard combined PCB board, and where it is used, in fact, it is widely used in mobile phone cameras, laptops, laser printing, medical, military, aviation and other products.

As a major consumer electronics manufacturing country in the world, there is huge demand for flexible circuit boards in China, and domestic flexible circuit board companies are welcoming rapid development.

Huang Wei, an academician of the Chinese Academy of Sciences, said that flexible electronic technology will drive a trillion-scale market, and it is an opportunity for China to strive for leapfrog development of the electronics industry and become a national pillar industry.

In recent years, flexible circuit boards have become a hot spot in domestic capital markets. In March last year, Suntech was listed on the "New Third Board" and entered the strategic innovation level in September of the same year; Xiamen Hongxin Electronics was listed on the GEM and was recently approved by the Securities Regulatory Commission; Jiangxi Helitai recently announced that it plans to acquire Lanpei Technology to obtain International leading FPC material technology.

Domestic FPC production capacity is expanding rapidly, but some experts pointed out that at present some core raw materials of FPC products, such as flexible copper clad laminates, conductive adhesive films, and shielding films, are still in the hands of foreign-funded enterprises. Domestic FPC domestic-funded manufacturers have weaker competitiveness in participating in the international market. , Sales are mainly concentrated in the domestic market, the overall market share is low.
