3. Trace width, thickness and spacing conform the standards to avoid short circuit, open circuit and circuit heat.

4. Copper surface is not easy to fall off when temperature goes up.

5. Copper surface is difficult to be oxidized, which will influence the assembly of components.

6. No extra electromagnetic radiation

7. The profile is not deformed, so as to avoid the deformation of the shell and dislocation of screw holes after installation.

8. High temperature, high humidity and special environment should be taken into consideration.
