Consider the choice of substrate The substrate of PCB board can be divided into two types: organic material and inorganic material, each material has its own The unique advantage lies. Therefore, the determination of the type of substrate considers various properties such as dielectric properties, copper foil type, thickness of the base groove, and processability characteristics. Among them, the thickness of the surface copper foil is a key factor affecting the performance of this circuit board. Generally speaking, the thinner the thickness, the more convenient the etching and the improvement of the precision of the graphics. 2. Consider the setting of the production environment. The environment of the PCB board processing and production workshop is also a very important aspect. The regulation of environmental temperature and humidity are both crucial factors. If the ambient temperature changes too significantly, it may cause the holes on the base plate to break. If the environmental humidity is too high, nuclear energy will have an adverse effect on the performance of the substrate with strong water absorption, specifically in terms of dielectric properties. Therefore, it is particularly important to maintain proper environmental conditions during PCB processing and production. 3. Consider the choice of process flow. The production of PCB will be affected by many factors, such as the number of layers, punching process, surface coating treatment and other process processes will affect the quality of the finished PCB board. Therefore, in the face of these technological process environments, PCB board processing and production are fully considered in combination with the characteristics of the production equipment, and can be flexibly adjusted according to the types of PCB boards and processing requirements. It can be concluded from the above that PCB board processing and production need to consider the choice of substrate, the setting of the production environment, and the choice of process flow. At the same time, the processing and blanking methods of PCB engineering materials are also an aspect that needs to be carefully selected, which is closely related to the smoothness of the printed circuit board.
