[0002] Printed circuit boards, also known as printed wiring boards, are important electronic components. They are the support of electronic components and the carrier of electrical connections of electronic components. Printed circuit boards are divided into single-sided, double-sided and multi-layer boards. In the existing pressing process production, single substrate raw materials are widely used for manual alignment, and then pressed with traditional presses to form circuit boards. The existing stamping dies have structural deficiencies, which makes it difficult to operate the circuit boards when taking them out after stamping, and they are easy to fall and be damaged. The work efficiency is low, and a lot of man-hours and traditional pressing equipment are required, which wastes manpower and electricity resources in production.

[0003] Technical solutions for printed circuit board pressing equipment have also appeared in the prior art. For example, a Chinese patent with announcement number CN107413922B discloses a stamping mold for a flexible circuit board, including a left fixed seat, a right fixed seat, a guide rod, a left mold seat, a middle mold seat, a right mold seat, an electromagnet No. 1, an electromagnet No. 2, an elastic member, a damping member, a material storage box, a control switch and a controller. The left fixed seat and the right fixed seat are relatively fixedly arranged on the left and right; the guide rod is fixed between the left fixed seat and the right fixed seat; the left mold seat, the middle mold seat and the right mold seat are installed on the guide rod in sequence from left to right; the electromagnet No. 1 and the electromagnet No. 2 are installed on the left fixed seat and the right fixed seat respectively; the elastic member is mounted on the guide rod; the damping member is installed on the middle mold seat; the material storage box is located below the middle mold seat; and the control switch is used to energize the electromagnet No. 1 and the electromagnet No. 2.
