I just realized that most cheap PCB’s are normally green, especially older ones. Where as custom or higher end PCB’s range wildly in color, why is that?
In: Technology
Green was the coloration given to the conformal coating that covered the first fiberglass boards. There were also some other colors such as brown or orange, but green won out as the most recognizable and aesthetically pleasing default.
But, it doesn’t really matter. It is just a dyed coating, it could be any color. These days they are green because people expect them to be green, no other reason.
