At present, in the field of electronic product processing, PCB boards are indispensable as one of the important electronic components. At present, there are many types of PCB boards, such as high-frequency PCB boards, microwave PCB boards and other types of printed circuit boards that have gained a certain reputation in the market.


1. Consider the choice of substrate

The base material of PCB board can be divided into two types: organic material and inorganic material. Each material has its unique advantages. Therefore, the determination of the type of substrate considers various properties such as dielectric properties, copper foil type, base groove thickness, and processability characteristics. Among them, the thickness of the surface copper foil is a key factor affecting the performance of this printed 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, and the regulation of environmental temperature and environmental 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 necessary to maintain proper environmental conditions during PCB processing and production.

3. Consider the choice of process flow


The production of PCB is easily affected by many factors, and the number of layers, punching process, surface coating treatment and other technological processes will affect the quality of the finished PCB board. Therefore, for these process environments, PCB 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.


In summary from the above description, PCB processing needs to consider the choice of substrate, consider the setting of the production environment, and consider the choice of process flow. At the same time, the processing and blanking methods of the engineering materials of the PCB board are also an aspect that needs to be carefully selected, which is closely related to the smoothness of the finished circuit printed board.
