1. Green PCB
In the production schedule, most of the printed circuit boards (PCBs) are green, and that’s because of the solder mask on the PCB. Its existence protects the copper circuit printed on the glass fiber core to prevent short circuits and mistakes in soldering. The color of the solder mask determines the appearance of the circuit board. In PCB board maker, most of the solder mask is green, so the PCB protected by them becomes green. In addition, there is another explanation. In the beginning, PCBs were used for the military (military radios). To hide their role, PCBs were deliberately made green due to the industrial practice of military production. This industrial practice has also been retained when PCBs are used for civilian purposes.

2. The Types of PCB’s Color
In addition to green PCB, in modern industrial production, PCBs have other color options, which can help distinguish different types of printed circuit board. The common colors of PCBs are green, blue, black, red, and white. In addition, the colors can be customized according to customer requirements.
