[0002] PCB, the Chinese name for printed circuit board, is also called printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. When producing PCB boards, multiple PCB boards need to be pressed together.

[0003] For example, a multi-layer PCB board pressing device with the authorization announcement number CN214852080U includes a frame, a pressing operation room is arranged at the upper end of the frame, and the pressing operation room includes an operating table and side panels symmetrically arranged on both sides of the operating table; although the above document can realize that the electric heating device does not generate open flames and smoke, it can control fire hazards and reduce air pollution; it is convenient to put in the PCB board, and when the lower pressing plate moves outward, the upper pressing plate is scrubbed by a brush roller to prevent foreign matter from damaging the PCB board; but when in use, when the pressing device presses the multi-layer PCB board, the multi-layer PCB board is placed on the base and pressed by the pressing plate, Since only one base and a pressing plate are provided inside the device, only one multi-layer PCB board can be pressed at a time, and it takes a long time to press all the multi-layer PCB boards, thereby reducing the working efficiency of the pressing device; at the same time, when the pressing device is pressing the multi-layer PCB board, since the base and the pressing plate need to heat the multi-layer PCB board, the heat on the base and the pressing plate will be transferred to the multi-layer PCB board through heat transfer. After the multi-layer PCB board is pressed, the staff needs to remove it, resulting in the high temperature on the surface of the multi-layer PCB board easily scalding the staff when taking it out, thereby reducing the safety of the pressing device.
