Problems solved by technology

[0003] Since the electronic components need to pass through the holes on the board when they are connected to the board, if there are defects in the holes used to connect the electronic components, for example, there is a sharp edge, it will easily lead to short circuit or open circuit of the PCB, and even lead to the scrapping of the product
Therefore, in the process of preparing the PCB, the sharp edges generated by the drilling need to be strictly controlled. Taking the single-sided board as an example, before drilling the single-sided board, the copper side of the single-sided board placed on the backing board should face the First, cover the single panel with aluminum sheet, and then drill the single panel. Due to the covering effect of the aluminum plate, the height of the batch front generated by the drilling process on the copper surface of the single panel can be greatly reduced, but it is still not possible to completely Avoid the sharpening of the copper surface of the single-sided board due to drilling. As a result, the copper surface of the single-sided board still needs to be polished to remove the sharpening after drilling. The debris generated by the front can easily lead to bad

Abstract

The drilling method for the single-sided board comprises the following steps that S101, a base plate is placed on a drilling table top, the single-sided board is placed on the base plate, the single-sided board is fixed to the drilling table top, and the copper face of the single-sided board faces the base plate; and S201, drilling is conducted on the single-sided board placed on the base plate, and a drill bit feeds from one side of the medium face of the single-sided board. According to the single-sided board machined through the drilling method, burrs generated after drilling are all located on the medium face of the single-sided board, and due to the fact that the medium face of the single-sided board is not provided with wires and copper, even if the burrs on the medium face of the single-sided board need to be polished subsequently, the wires are not prone to being damaged in the polishing process, and the service life of the single-sided board is prolonged. Therefore, the quality of the single-sided board after drilling is ensured. And moreover, the use of an aluminum sheet is avoided, so that the processing efficiency is improved, the quality is ensured, and the cost of a drilling procedure is greatly reduced.

Description

technical field [0001] The invention relates to a method for drilling a circuit board, in particular to a method for drilling a single panel and the obtained single panel. Background technique [0002] Printed Circuit Board (PCB for short) achieves circuit miniaturization and visualization by designing circuits on the board and connecting electronic components to the circuits on the board. For mass production of fixed circuits and optimization of electrical appliances Layout plays an important role. [0003] Since the electronic components need to pass through the holes on the board when they are connected to the board, if there are defects in the holes used to connect the electronic components, for example, there is a sharp edge, it is easy to cause a short circuit or open circuit on the PCB, and even cause the product to be scrapped. Therefore, in the process of preparing the PCB, the sharp edges generated by the drilling need to be strictly controlled. Taking the single-...
