　　First: distinguish the quality of the circuit board from the appearance

　　Under normal circumstances, the appearance of the PCB line board can be analyzed and judged through three aspects;

　　1. Standard rules of size and thickness. The thickness of the circuit board on the standard circuit board is different. Customers can measure and check the thickness and specifications of their products according to the thickness and specifications of their products.

　　2. Light and color. The external circuit board has ink coverage, and the circuit board can play an insulation. If the color of the board is not bright, less ink, the thermal insulation board itself is not good.

　　3. The appearance of the weld. Due to the large number of parts, if the welding is not well welded and the parts of the parts are easy to fall off, it seriously affects the welding quality of the circuit board. The appearance is good, and the interface is stronger.

　　Second: High -quality circuit boards need to meet the following requirements

　　1. After the component is installed, the telephone should be easy to use, that is, the electrical connection must meet the requirements;

　　2. The line width, thickness, and line distance of the line meet the requirements to avoid the line heat, disconnection, and short circuit;

　　3. It is not easy to fall off by high temperature copper skin;

　　4. The surface of the copper is not easy to oxidize, affects the speed of installation, and it will be broken soon after oxidation;

　　5. No additional electromagnetic radiation;

　　6. The shape is not deformed, so as not to deform the shell after installation. Now they are all mechanized installation. The deformation errors of the holes and lines and design of the circuit board should be within the allowable range;

　　7, and high temperature, high humidity and special environment should also be considered within the scope of consideration;

　　8. Surface mechanical performance meets the installation requirements;
