Якасная Друкаванай платы must meet the following requirements

1. After the components are installed, the phone should be easy to use, that is, the electrical connection should meet the requirements;
2, line width, line thickness, line distance meet the requirements, so as to avoid line heating, circuit breaker, and short circuit;
3, by high temperature copper skin is not easy to fall off;
4, copper surface is not easy to oxidize, affect the installation speed, after oxidation with soon broken;
5, no additional electromagnetic radiation;
6, the shape is not deformed, so as to avoid the deformation of the shell after installation, screw hole dislocation. Now are mechanized installation, the hole position of the circuit board and the deformation error of the line and the design should be within the allowed range;
7, and high temperature, high humidity and resistance to special environment should also be considered within the scope;
8, the mechanical properties of the surface should meet the installation requirements;
The above is the method of judging the quality of PCB BOARD CAM OEM board, when buying Друкаванай платы, we must sharpen our eyes.
