That is just the conventional color of the insulating varnish "mask" used to protect the board. It could be a different color, but green was selected as it contrasts well with copper traces allowing them to be seen through the "mask". Up until the late 1950's, circuit boards were usually brown in color. The brown boards had no "mask" on them, the traces were protected with solder dip. Brown is the color of the paper-epoxy or paper-phenolic board material used.

What is the use of a track cutter?
Cuts copper traces of printed circuit boards to allow changes.
What you can do after degree in electronics and telecommunications?
You could go into teaching or you could get a job manufacturing circuits/circuit boards.
What is the lifetime of printed circuit board?
Depends on the material it's constructed from, the application for which it's being used and the atmospherics to which it's exposed. I have printed circuit boards from the very first model of an RCA transistor radio made in 1957 and the circuit board as well as the electronics still work.
What can printed circuit boards be used for?
PCB or printed circuit board are copper clad that are chemically etched to establish connections with parts installed on it making it a working circuit Today, just about every electronic appliance in your home contains a printed circuit board of some type: computers, printers, televisions, stereos, musical instrument amplifiers and synthesizers, digital clocks, microwave ovens, telephone answering machines and even cell phones. The "motherboard" in a computer is the main printed circuit board that is the heart of a computer. Other circuit boards inside a computer performs functions such as RAM (random access memory), power supplies, modems and video "cards."
What is the green thing call inside of electronics?
That would probably be the circuit board.
Why are motherboards green in color?
That is the general color for PCBs (printed circuit boards) back then, as the general process for making circuit boards is having a board coated in copper etched in a specific pattern (using a etching chemical to eat away the copper) obtained from the engineer that designed the circuit. Nowadays computer system boards do not look like the traditional green as manufacturers may shift to slightly different methods of producing their boards.
What country can you get circuit board?
Taiwan has good quality circuit boards. So, you can get circuit boards from there.SHARAN
Why do you use green masking and not any other ordinary color in printed circuit boards?
Green, Red, Purple, Gold, Blue are all used.
Are all motherboards green?
No. While green is the most common color for printed circuit boards, any color, such as orange, blue, red, or purple can also be used.
Where can someone find a printed circuit board design online?
You can find a printed circuit board design online in some blogs or message boards that are interested in designing circuit boards. You can also find some designs on websites that sell kits and circuit boards.
Are circuit boards dangerous to be used?
Circuit boards are not dangerous to use and they are not some type of skateboard. There are tons of varieties of circuit boards for different things you are trying to control. You'd need to ask a more specific answer since there are so many types.
Circuit boards that provide more memory or control peripheral devices are called?
Expansion Boards
What percentage of electronic connectors sold in the U.S. were printed circuit boards?
About one-third of electronic connectors sold in the United States are printed circuit boards.
What are most of the components in a PC mounted on?
Circuit boards
What in a computer holds all circuit boards?
It is the motherboard.
What holds all of the circuit boards in the computer?
The motherboard
