The reason why the circuit board bends

With the rapid development of modern science and technology, we are increasingly inseparable from all kinds of electronic products in our lives. Many friends with deep curiosity like to take some old or bad electronic products apart. At this time, we will find that there are some boards in these electronic products, but the lines inside these boards are too complicated, right? Why is the circuit inside the board bent and the ordinary people can't understand it? Can't the circuit board's lines be designed as straight lines?

    Why is the circuit board circuit designed to be curved? First, if the lines in the board are designed to be straight, the board area will increase by several times. In today's era of pursuing exquisiteness and compactness, the area of the circuit board is naturally as small as possible, otherwise it will directly affect the area of electronic products. It is estimated that people's requirements for electronic products are: in addition to the larger the screen, the others are getting smaller and smaller, and the thickness is as thin as possible.

    Secondly, even if we don't care about the size of the board, designing the lines in the board as straight lines will cause other problems. In the board, the line will definitely need to turn. If we design the lines in the board to be straight, the angle of the turn is ninety degrees. Because the line can easily produce large reflections when turning at ninety degrees, such a board can easily be broken during production. In this case, not only the waste of materials, but also the successful manufacture of the circuit board, it is easy to produce quality problems.

    Third, the lines on the board are designed to be curved to ensure signal stability. The design of the circuit board is a technical activity, and only the corresponding design can ensure the stability of the signal. The chip on the board can only work properly if the signal is not disturbed.

    Every twisted line on the board represents a different signal. If the lines on the board are designed to be straight, it is easy to cause interference between the signals, making our electronic equipment not working properly. If our cell phone signal is disturbed, it is likely that there is a problem with the board, so such a phone can almost be declared scrapped.
