Information and description about circuit board etching can be found on the internet on specific websites. One can get more information regarding circuit board etching by searching from other relevant sources. Alternatively, one can also consult a person with some knowledge in this matter to get detailed information.

You can use a Sharpie to create a simple circuit board by drawing the circuit paths directly onto a copper-clad board. First, clean the copper surface, then use the Sharpie to trace the desired circuit layout, ensuring the lines are thick enough to conduct electricity. After the drawing is complete, you can etch away the unmarked copper using a suitable etching solution, leaving only the traced paths. Finally, rinse off the etching solution, and you can solder components onto the remaining copper traces to complete the circuit.
The basic stages involved in making a pcb (printed circuit board ) are: Designing the traces on paper or an autocad style computer application. Using a transfer or mask to apply a resist to a copper clad board Spraying or putting the copper clad board into an etching bath of acid. The etching bath removes the copper that was not protected by the resist. Washing the etching solution off to stop the process. Removing the resist that protected the copper.
A circuit board or more precisely a printed circuit board (PCB) is a mechanical structure that provides support for mounting electronics and electrical components and connecting them with conducting traces or wires. PCBs are designed to perform a specific electrical or logical function. So what and how a circuit works will depend on its design. e.g. a circuit board in a TV processes audio/video TV signals. An audio amplifier circuit board amplifies and makes audio signals louder. Similarly various circuit boards in a Personal Computer perform different functions e.g. PC mother board, TV tuner card, USB/Firewire Card, Graphics cards are all circuit boards and perform different tasks. All of them need power (typically a DC voltage) for various components and circuits to work.
The metal commonly found on a circuit board is typically copper, which is used for creating conductive pathways for electrical signals. Copper is favored for its excellent conductivity and ease of etching during the manufacturing process. Additionally, circuit boards may have a thin layer of other metals, such as gold or tin, for soldering and protection against oxidation.

It is a process used in the making of printed circuit boards. A protective material is used to cover the traces that you want left on the PC board. The board is then submerged into an liquid that will etch the unprotected copper off of the board. This removed material then becomes the space between the protected material that you want to use for current caring traces to different components on the board.
