With the development of industrial robots, the demand of robot PCB is increasing gradually, but there are still many problems to be solved. Because many operation lines in PCB industry are non-standard products, in the process of robot application, they are limited by the existing operation space and the original equipment capacity. In the face of the influence of different PCB material factors, they also need to consider the application of various sensors to improve the robot's intelligence. Therefore, the robot PCB has high requirements for board precision and material.
