Description

Technical Field

[0001] The utility model relates to the field of copper-plated half-hole PCB board drilling, in particular to a copper-plated half-hole PCB board drilling device. Background Art

[0002] Many holes are designed on the PCB board, which are divided into through holes, installation positioning holes, plug-in holes, etc. according to their functions. If these holes have conduction requirements, copper will be plated in the holes, which are plated through holes---PTH holes. Holes that do not require conduction do not need copper plating, which are non-plated through holes---NPTH holes. Plated through holes are generally designed completely in the PCB board, but some designs require holes to be designed at the edge of the board, and only part of the hole shape needs to be retained. This is a copper-plated half hole, which is referred to as a half hole in the industry. Therefore, when drilling holes in the PCB board, a drilling device is required to drill holes. However, during the use of existing PCB board drilling devices, most of them have a relatively fixed structure, and the drilling position of the drilling device cannot be adjusted according to the size of the PCB board, which greatly reduces the convenience of using the drilling device. At the same time, the drilling knife of most drilling devices cannot be moved, and the drilling distance is irregular, which requires external adjustment and control, reducing work efficiency.
