In our daily life, there are many intelligent electrical appliances that bring us many conveniences, such as floor sweeping robots, dish washing robots, cooking robots, etc. among them, these robots inevitably need PCB boards with reliable quality in the assembly process

Rigid-flex board is a combination of flexible board and hard board. It is a circuit board formed by combining a thin layered flexible bottom layer with a rigid bottom layer, and then laminating it into a single component.The flexible board is used to replace the cable assembly to complete the highly reliable connection and transmission of power and electrical signals.The product can work stably and reliably for a long time under harsh environments such as high and low temperature, high humidity, vibration, salt spray, and low air pressure. At present, Jonhon Optronic has provided rigid and flexible printed board solutions for aviation, aerospace, ships, weapons and other fields.

In the 1980s, China began to enter the semiconductor industry. In the early days, semiconductor technology mainly relied on imports, while China mainly engaged in simple assembly and testing work. At that time, major enterprises such as Shanghai Hongli and East China Semiconductor had a significant gap between their product technology level and the international advanced level, but it laid the foundation for the Chinese semiconductor industry

Every time through AI flash, Guojin Securities said that semiconductor equipment parts play an important role in the industrial chain, with a large number, a wide variety and obvious market fragmentation characteristics
