Because it is made by electronic printing technology, it is called "printed" circuit board.

[0003] A multi-station transmission device is usually used when processing circuit boards. However, most of the existing multi-station transmission devices use a conveyor belt to transmit the circuit boards. However, this method has the problem of poor stability. Since the mounting base for the circuit board is directly placed on the conveyor belt, there will be problems such as offset during the operation of the conveyor belt. At the same time, during transmission, frequent starts and stops are usually required to meet the pause requirements between transportation distances. Long-term frequent starts and stops will cause the motor to overheat. Therefore, we propose a multi-station transmission device for circuit board processing. Utility Model Content
