Effect of corrosion on printed circuit board

Corrosion of electronic systems has been a significant issue in electronic industry nowadays. One of the most common corrosion type is the atmospheric corrosion. Therefore, even a small environmental impact can cause huge damages if the components are not well protected. When the device is in use, t...
