Why electronic circuit chips are green in color….??
This was selected as Best Answer I believe this is how it works… A non conductive core is made out of some type of resin, usually something like polyester resin you would find at a auto parts store to repair auto body damage. This core is coted on both sides with copper (in some cases a different material is used like gold). The board is then “printed” by removing the copper to separate the different circuits (lines on the board). This is done by etching the board with a chemical after printing a protective ink on the places you don’t want removed. Now you have a printed circuit board but it is tan and copper colored. You a little more work prepares the circuit board for soldering of various electronic pieces onto the board like microchips. The board is then coated with the soldering mask which prevents stray solder from bridging between two or more circuits on the board, it also prevents the circuits from corroding or being scratched or damaged in some way. This coating is the sourc
