4.A brief discussion on the self - control of circuit board.
The name of the circuit board is: circuit board,PCB board, aluminum substrate, high frequency board,PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc.The circuit board makes the circuit miniaturized and visualized, which plays an important role in the mass production and optimization of the fixed circuit.Method of self-made printed circuit board: 

First, saw the proper size of the copper plate.Clean the oxide and grease on the surface of copper foil.You can gently rub the skin with water, or scrub it with detergent, or use toothpaste, until you see yellow copper foil. 

Second, draw the printed circuit diagram according to the circuit requirements on the paper first, and then copy it to copper foil with carbon paper.It can also be drawn directly on the copper foil with a pencil. The lines should be light and thin.Use a small brush dipped in colored paint, tracing the lines along the copper foil.The line is fine and suitable, should not be connected can not have the paint.After waiting for paint dry, with double knife or other thin blade knife, carefully modified line, can't touch the bad need of painting, the line is smooth and beautiful, even thickness, and check the original circuit, check whether is wrong. 

Third, take a glass or enamel container, the size of the circuit board size.In the container, the solid ferric chloride is placed in the container, and the water is dissolved into a solution of ferric ferric chloride. The concentration of the mixture is generally regarded as the color, which is close to the dark brown color.The amount of solution can only be immersed in the circuit board.With a soft brush gently rinsed in copper foil surface, can make the corrosion quicker, but can't touch paint, after a period of time, with the paint of copper foil are left behind, the rest of the corroded by ferric chloride solution. 

Fourth, the corrosion good circuit board is rinsed with clean water, use fine sand skin to gently wipe off the paint.You can also scrub with banana water.Dry the water and drill holes in the corresponding position with a bit of about 1 mm in diameter.In the end, the rosin is dissolved in anhydrous alcohol to make a soldering protective agent on the circuit board.The printed circuit board is made.
