The third that look golden/yellow is a clear coat where you see the copper below.There is a good reason to have a color and that is so it is simpler to see where the solder resist is and where you have exposed copper solder pads.I suspect that the traditional color is green because you can see the undrelaying copper traces trough it quite easy compared to a lot of other colors and that is quite relaxant and easy for the eyes to look if for the people that mounted and soldered the component on it. Manufacturing from they was introduced in the 1940 until surface mounted part placed by machines become common in the 1980s the component was put there by humans. So not stressfull to look at and good contrast to components and printed stuff on the board was important.Today when almost all components are mounted by machines the colors is not relevant for manufacture but can be that for consumers in products where they are exposed like in computers. So read and black computer motherboard is more common then green-0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsApp DarkAlman Added an answer on May 29, 2019 at 12:26 am Circuits boards don’t have to be green, they can come in a variety of colors from black to bright red and yellow.Green just happens to be the most common color because the glass-epoxy coating is naturally green.Circuit boards are naturally yellow/brown until an epoxy coating is applied to circuit boards. The coating is used for a variety of reasons including that it’s non conductive.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
