1.Components installation, the phone is better use, that is, the electrical connection should meet the requirements.
2.The line width, thickness, spacing of the High Quality PCB Board meet the requirements, so as to avoid line heating, open circuit and short circuit.
3.The high temperature copper skin is not easy to fall off.
4.Copper surface is not easy to oxidize, oxidation soon broke down.
5.No additional electromagnetic radiation.
6.The shape is not deformed, so as to avoid the deformation of the shell. Now all the mechanical installation, the circuit board hole position and line and design deformation error should be within the allowable range.
7.High temperature, high humidity and resistance to special environment should be considered within the scope.
8.The surface mechanical properties should meet the installation requirements.
The above information can judge the Industry PCB, you can choose better quality of printed circuit board.
