Problems solved by technology
In this way of processing, the printed circuit board is easy to move during the processing process, resulting in poor processing of the printed circuit board; in addition, the tape is used to fix it, and the tape cannot be reused. In the continuous production process, the tape needs to be replaced continuously, resulting in a serious waste of tape. , affect the environment, and after the tape is torn off, the glue on the tape will stick to the printed circuit board, which is not easy to remove

Embodiment Construction
[0039] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0040] This embodiment provides a drilling method for printed circuit boards, which can be used for automatic or semi-automatic processing of printed circuit boards.
[0041] Such as figure 1 As shown, before drilling the printed circuit board, it is necessary to fix the printed circuit board on the workbench, so as to prevent the position of the printed circuit board from moving during the processing. Wherein, the workbench is generally made of aluminum or iron material. In order to avoid static electricity between the printed circuit board and the workbench during processing, a bakelite board is also provided on the workbench. Bakelite has the chara...

The invention discloses a drilling processing method and a drilling system for a printed circuit board, and relates to the technical field of printed circuit board processing. The drilling processingmethod of the printed circuit board comprises: S1, fixing the printed circuit board to the workbench; S2, placing the aluminum sheet on the printed circuit board; S3, analyzing and determining the connection position of the printed circuit board and the aluminum sheet, and fixing the connection position by rivets or pins; and S4, drilling the printed circuit board. In the drilling processing method of the printed circuit board, the aluminum sheet and the printed circuit board are fixed by pins or rivets with no need to be fixed by a tape, which has better fixing effect, is capable of avoidingthe waste of the tape and reducing the flashing of the printed circuit board, and is beneficial to the improvement of product quality. In order to prevent the cooperation between the printed circuit board and the rivets or pins from damaging the content holes and lines of the inner layer of the printed circuit board, the connection position of the printed circuit board and the aluminum sheet needsto be analyzed and determined before fixing the aluminum sheet and the printed circuit board, thereby ensuring the processing quality of the printed circuit board.
Description
technical field [0001] The invention relates to the technical field of printed circuit board processing, in particular to a drilling method and a drilling system for a printed circuit board. Background technique [0002] Printed Circuit Board (PCB), also known as printed circuit board, printed circuit board, or printed board for short, is a provider of electrical connections for electronic components. The printed circuit board is based on an insulating board and cut to a certain size. At least one conductive pattern is attached to it, and there are inner holes (such as component holes, fastening holes, metallized holes, etc.), which are used to replace the electronic components of the previous devices. The chassis of components, and realize the interconnection between electronic components. [0003] Printed circuit boards are generally drilled with CNC machining equipment. When drilling, the printed circuit board is fixed on the workbench, the printed circuit board is prov...
