At present, in the electronic product processing industry, Papan PCB is indispensable as one of the key electronic components. At present, PCB board has various types, such as high frequency PCB board, microwave heating PCB board and other types of printed PCB board has already made a certain reputation in the sales market. PCB manufacturers have special processing techniques for various types of PCB boards. But in general, PCB board production and processing must be considered two or three levels.

1. Consider the selection of plate

The key of PCB board can be divided into organic chemical raw materials and inorganic raw materials two types, each raw material often has its unique advantages. Therefore, the definite type of plate takes into account the dielectric properties, types of copper foil, the thickness of the base groove, and the characteristics of production and processing. Among them, the thickness of copper foil surface is the primary condition to harm the characteristics of printed PCB board. In general, the thinner the thickness, for the convenient etching process and improve the pattern of high precision has advantages.

2. Take into account the setting of the production process

The natural environment of PCB board production and processing workshop is a very critical level, and the control of working temperature and relative humidity of air are particularly important elements. If the working temperature change is too obvious, it may cause the rotating hole on the plate to break. If the relative humidity of the air is too large, nuclear power generation has bad harm to the characteristics of the plate with strong bibitive ability, mainly shown in the dielectric performance level. Therefore, it is necessary to maintain moderate natural environment standards in PCB board production and manufacturing.

3. Consider the selection of production process

PCB manufacturing is very easy to meet the harm of a variety of elements, production and processing layer number, hole processing technology, surface coating solution and other production processes will lead to harm PCB board quality. Therefore, considering the natural environment of this production process, PCB board production and processing is integrated with the characteristics of manufacturing machinery and equipment, it can be flexibly adjusted according to the type of PCB board and the requirements of production and processing.

From the left and right, the selection of PCB board, the setting of production process and the selection of production process must be taken into account in the production and processing of PCB board. In addition, the construction materials of PCB board and the way of opening are a level that must be carefully chosen, which is closely related to the glossiness of the plate of the finished products of the power circuit packaging printing board.
