Description

[0002] A PCB board generally refers to a circuit board. The PCB board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. The printed circuit board (PCB) can be classified into single-sided boards, double-sided boards, and multi-layer circuit boards according to the number of layers. The PCB board turning machine is one of the commonly used devices in PCB board processing, and can turn the other side of the PCB board upwards.
