1. Printed board is made of resin, glass fiber cloth and copper foil, and the material is complicated. Therefore, affecting the borehole
The processing is more due to Qin, and the processing process is slightly inadvertent, which may directly affect the quality of the hole. In severe cases, it will result in scrapping. Therefore, if an abnormality is found in the borehole over-product, the problem must be analyzed in time, and the corresponding process countermeasures should be corrected in time to produce a low-cost, high-quality printed board.

2. The quality of the borehole is related to the structure and characteristics of the substrate, the performance of the equipment, the working environment, the application of the backing plate, the quality of the drill bit and the cutting process conditions. The specific reasons for analyzing the quality of the borehole can be analyzed from the specific conditions of these influencing factors to find out the exact influencing factors, so as to make targeted improvement measures.

3. Some factors affecting the quality of drilling are mutually restrictive. Sometimes several factors act at the same time and affect quality. For example, a substrate with a higher glass transition temperature (Tg) and a substrate having a lower glass transition temperature, due to the different brittleness of the substrate, the conditions for drilling should be different, and the substrate having a higher glass transition temperature. The feed rate of the drill hole is lower. Therefore, it is necessary to develop a proper drilling procedure and select the appropriate drilling method before drilling, and to understand the structural characteristics and physical and chemical properties of the substrate.
