Problems solved by technology

However, for PCBs made of composite pressed multi-layer materials, the micro-drills are likely to cause rough holes on the PCB during the drilling process, which affects the processing quality.
[0005] In view of the related technologies mentioned above, the inventor believes that in the process of drilling the PCB with the traditional micro-drill, after the micro-drill has been used for a long time, the micro-drill may easily cause the rough surface of the PCB, making the quality of the processed PCB not tall

Abstract

The invention relates to a PCD microbit and relates to the technical field of microbits, the PCD microbit comprises a clamping part and a drilling part which are sequentially connected, the clamping part is used for being fixed to drilling equipment, the drilling part comprises a drilling section and a cutting section, the clamping part, the drilling section and the cutting section are coaxially arranged, one end of the drilling section is connected with the clamping part, and the other end of the drilling section is connected with the cutting section. The other end of the drill rod is connected with the cutting section, and the cutting section is used for drilling a PCB. Through the cutting section, the drilling strength of the drilling section can be improved, abrasion of the cutting section in the drilling process is reduced, and the service life of the drilling section can be prolonged. Meanwhile, through the cutting section, the PCB machining quality of the drilling section can be improved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of micro-drills, in particular to a PCD micro-drill. Background technique [0002] At present, with the development of science and technology, the printed circuit board (PCB) is used as the carrier for the electrical interconnection of electronic components. Almost every electronic device needs to use PCB. PCB is widely used in computer, communication electronic equipment, military weapon system and other fields. [0003] As the carrier of the integrated circuit board, with the high development of integrated circuits, it is necessary to open holes on the highly integrated PCB so that the PCB board can be equipped with highly integrated integrated circuits. Therefore, in the process of manufacturing the PCB, it is usually necessary to open a hole on the PCB to make the hole diameter smaller. Usually, the PCB needs to be drilled with a micro drill to get the IC board to the required size. [0004] Most of t...
