For PCB classification by color, we will have to know solder mask. Solder mask is a thin protective layer of polymer that is applied to the traces of the printed circuit board during its manufacturing. The solder mask protects the copper traces from oxidation. For any printed circuit board, color is one of the critical design considerations. Green has been the most favored solder mask color always. We offer green, and a variety of solder mask colors like white, black, blue, red, yellow, purple and so on to meet your requirements.
