This design helps to achieve accurate positioning and separation of the PCB board body 2, ensures that each part can be accurately cut or separated according to the preset position during the manufacturing or processing process, and improves production efficiency and product quality.

[0028] An inner side of the first dividing groove 5 is inclined, and an angle α between the inner inclined side of the PCB body 2 and the edge of the PCB body 2 is greater than or equal to 20 degrees and less than or equal to 65 degrees.
