A motherboard is a circuit board that connects all the components in a computer. Motherboards come in various sizes and colours, depending on what kind of computer you’re making.
Due to the solder mask being laid on top of the basic materials, the motherboard’s backdrop appears green.
Surface-mounted components started to appear more often and were covered with a solid epoxy in the 1960s on circuit boards like the motherboard.
Why is PCB Green in Colour?
It is because the solder mask, which guards against short circuits, incorrect soldering, etc., shields the copper circuitry printed on the fibreglass core.
There are different theories on why it is traditionally green including the colour or the resins originally used to manufacture PCBs, the army’s role in the development of PCBs in the 1950s or simply industry convention.
Does the Colour of PCB Matter?
Printed circuit boards, or PCBs, provide a foundation for connecting electronic parts. Its colour has no direct bearing on how well it performs, and the colour of the solder mask has no bearing on how well the electric system performs.
Final Thoughts: Why Motherboard is Green in Colour?
Green is the standard colour for solder resist that is coated to the exterior layers of circuit boards to prevent stray solder from migrating when components are soldered on.
