2024-03-01
1. It is required that the telephone should be easy to use after the components are installed, that is, the electrical connection should meet the requirements;
2. The line width, line thickness and line distance of the line meet the requirements to avoid line heating, open circuit and short circuit;
3. by high temperature copper is not easy to fall off;
The copper surface is not easy to oxidize, which affects the installation speed, and it will be broken soon after oxidation;
5. No additional electromagnetic radiation;
6. The shape is not deformed to avoid deformation of the shell after installation and dislocation of the screw holes. Now it is mechanized installation, the hole position of the circuit board and the deformation error of the line and the design should be within the allowable range;
7. And high temperature, high humidity and resistance to special environment should also be within the scope of consideration;
8. The mechanical properties of the surface should meet the installation requirements;
