The Hidden Reason 99% of Circuit Boards are Green.
Ever notice that no matter what electronic device you open, the circuit board inside is that distinct shade of green? We usually think it’s just a standard manufacturing choice, but the truth is far weirder. It involves a chemical accident, a strict military mandate, unique human biology, and 60 years of economic optimization. In this video, we break down: The difference between the bare board and the solder mask. How epoxy resin was chosen in the 1960s, creating the color. Why the US Military made it the global standard. How your eye's sensitivity to green gave it a long-term advantage. The real cost of going off-script (and why Apple can afford black boards). It’s an incredible story of a mistake that got really, really good at surviving. If you’ve ever wondered why your electronics look the way they do, this is the history you were never supposed to see.
