In today's electronic product industry, PCB is the most indispensable key component in the entire electronic product. Since there are many fields involved in PCB manufacturing, if you do not participate in the PCB production process during the PCB design operation, it is conceivable that in the end, it will directly lead to more emphasis on performance and functions in the design process. In this case, the difficulty of product processing is not considered, because PCB manufacturers have special production and processing techniques for various types of boards. Therefore, the following issues must be considered in the processing and production of pcb boards.

First, the choice of plate

PCB sheets are divided into two categories: organic chemical raw materials and inorganic raw materials. The choice of sheet type should be determined in combination with the thickness of the base groove, electrical properties, type of copper foil, production and processing characteristics and other factors.

2. Environmental Control

The indoor environment of the PCB manufacturing workshop is also a key issue, and the control of working temperature and humidity is particularly important. If the temperature is too high, the holes in the board may crack. Secondly, if the humidity is too high, it will affect the strong water absorption properties of the sheet, mainly in terms of dielectric properties and electrical properties. Therefore, it is necessary to maintain a standard natural environment during the production and processing of pcb boards.

3. Plate vias are blocked

For example, PCB surface mount boards, especially BGA and IC mounts, have higher requirements for vias and plug holes. It must be flat, convex and concave plus or minus 1 mil, and there must be no red or tin on the edge of the via. Due to the complex hole plugging process and the long process flow, it increases the difficulty of process control. The oil will drip during hot air leveling or green oil solder mask testing. Once solidified, the oil will explode and other problems will occur. So we have to do both solder mask and plug holes on the board.
