Why Are PCBA Boards Green?

As society advances rapidly and the market for electronic products thrives, many individuals are entering the industry and partnering with electronic OEMs for production. These OEMs supply the necessary materials and raw components, while PCBA factories handle the processing.

The predominant green color of PCBA boards is attributed to the solder resist, a vital component of the manufacturing process. The solder resist plays a crucial role in preventing solder from unintentionally bridging between components, extending the device’s lifespan, and safeguarding the circuit from oxidation and corrosion.

While green remains the most prevalent color for solder masks on PCBA boards, they are also available in a variety of other colors such as white, yellow, red, blue, matte shades, and even unique options like chrysanthemum, purple, black, and bright green.
