Technical Field

[0001] The utility model relates to the technical field of circuit board pressing, in particular to a multi-layer circuit board pressing device. Background Art

[0002] A multi-layer circuit board pressing device is a device used for pressing and processing multi-layer circuit boards. It is widely used in the production and processing of multi-layer circuit boards. As the demand for the use of multi-layer circuit board pressing devices gradually increases, the existing multi-layer circuit board pressing devices can no longer meet people's needs. Therefore, a more convenient multi-layer circuit board pressing device is needed.

[0003] When the existing multi-layer circuit board pressing device is used, it is impossible to clamp and position the multi-layer circuit board during the pressing process, which is inconvenient to fix the position of the multi-layer circuit board during processing, resulting in the multi-layer circuit board easily deviating during pressing. In addition, when the existing pressing device is used to press the circuit board, it is usually necessary to fix the position before pressing, and it is impossible to fix the position of the multi-layer circuit board at the same time during the pressing process, resulting in low pressing efficiency.

[0004] To this end, we propose a multi-layer circuit board pressing device. Utility Model Content
