High Quality PCB Board Features include below aspects:
After the components are assembled properly onto the PCB board, the electronic device should be easy to use, that is, the electrical connection should meet the requirements;
The track width, track thickness and track spacing on the PCB board meet the requirements, so as to avoid heating, breaking, and short circuit of the track;
The copper foil it is not easy to fall off due to high temperature processing;
the copper foil surface is not easy to oxidize, affecting the assembling speed, it will be broken soon after oxidation;
There is no additional electromagnetic radiation from the circuitry pattern;
The shape of PCB board is not deformed, so as to avoid deformation of the outer casing after installation and the screw holes are misaligned. Now it is mechanized installation, the hole position on the printed circuit board and the deformation error of the track should be within the allowable range;
High temperature, high humidity and special environment terms should also be considered;
The mechanical properties of the surface should meet the installation requirements;
The above is the method for judging the GOOD quality of the PCB circuit board when purchasing the PCB circuit board.
