Soft and hard combined board is a new type of printed circuit board with durability and adaptability, which is used for three-dimensional assembly under different assemblies. It can be divided into two categories: soft and hard combined board and soft and hard combined board. The main difference lies in the material, structure and some differences.The combination of soft and hard plate can effectively reduce the assembly size of electronic products, avoid on-line error, realize light, intelligent, small volume, and strengthen the assembly flexibility.It is the main product of the electronic industry and has been widely used and valued.

The combination of soft and hard board was popular in Europe, America, Japan and other developed countries at the beginning. After the reform and opening up, it also became popular in China. It is mainly used in consumer electronics, medical machinery, automobile electronics, precision instruments, aerospace and other applications.Now the combination of hard and soft board is not very perfect, there is still room for development in the market.The soft-hard combination board of deep connection circuit is mainly used in LED lighting, military aerial photography, smart home, medical products, wearable devices, high-frequency antenna board and other fields.

This eight-layer hard and soft plate is used for military aerial photography. The upper and lower structure design is asymmetric

Medical products with six layers of hard and soft plate.
