As shown in fig. 5, the spacing distance L1 between the plurality of milling flutes 30 is 40mm, and the number of the milling flutes 30 is reasonably arranged, so that the function of the milling flutes 30 can be maximized, and the cost of the process flow can be controlled.

According to an exemplary embodiment, at least one end of the milled grooves 30 extends toward the PCB board 10 side, and a connection structure 40 is formed between adjacent milled grooves 30.

For example, as shown in fig. 4, one or both ends of the milled grooves 30 extend toward the PCB board 10 side, so that a connection structure 40 is formed between the adjacent milled grooves 30.

One end of the connecting structure 40 is connected to the PCB board 10, the other end of the connecting structure 40 is connected to the waste board 20, and the width of the end of the connecting structure 40 connected to the PCB board 10 is smaller than the width of the end of the connecting structure 40 connected to the waste board 20.

For example, as shown in fig. 4, the width of the connecting structure 40 connected to the PCB board 10 is smaller than the width of the connecting structure 40 connected to the waste board 20, so that the connecting structure 40 has a structure with a wide top and a narrow bottom.

When the PCB board 10 and the waste board 20 of the PCB panel 1 are separated, an external force may be concentrated between the PCB board 10 and the waste board 20, i.e., the connection structure 40 may receive the external force. Because the connecting structure 40 is a symmetrical structure, the end of the connecting structure 40 connected with the PCB board 10 is subjected to a uniform external force, so that the PCB connecting board 1 is disconnected at the end of the connecting structure 40 connected with the PCB board 10.

When the PCB panel 1 is divided, the milled groove 30 is cut at the end of the connecting structure 40 connected to the PCB panel 10. Because the both ends of milling flutes 30 are circular-arc structure, consequently, milling flutes 30 can be stayed to the vast majority of deckle edge that produces on milling flutes 30, because the deckle edge that PCB even board 1 divides the board production can not surpass the milling flutes 30 of PCB board 10 side, consequently can not exert an influence to the later stage process operation of PCB board 10.
