Why the lines on the PCB circuit board are bent

First of all, if the circuit in the PCB circuit board is designed to be straight, the area of the circuit board will increase several times. In this era of pursuing exquisiteness and compactness, the area of PCB 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: Except for the larger the screen, the other things are getting smaller and smaller, and the thickness should be as thin as possible.

Secondly, even if we do not care about the size of the PCB circuit board and design the lines in the PCB circuit board to be straight, it will also cause other problems. In the circuit board, the line will definitely need to be turned. If we design the circuit board in a straight line, the angle of the turn will reach ninety degrees. Because the circuit is easy to produce a lot of reflection when turning at ninety degrees, such a circuit board is easy to be broken during the production process. In this case, not only will it cause waste of materials, but even if the circuit board is successfully manufactured, it is also prone to quality problems.

Third, the circuit on the PCB circuit board is designed to be bent to ensure the stability of the signal. The design of the PCB circuit board is a kind of technical activity, and only the corresponding design can ensure the stability of the signal. Only when the signal is not disturbed, the chip on the circuit board can work normally.

Each curved line on the PCB circuit board represents a different signal. If the circuit on the PCB circuit board is designed as a straight line, it is easy to cause mutual interference between the signals, making our electronic equipment unable to work normally. If the signal of our mobile phone is interfered, it is likely that there is a problem with the circuit board, then such a mobile phone can almost be declared scrapped.

PCB circuit board is constructed by devices, capacitors, diodes, etc., these many lines constitute a complete circuit. If you are using a speaker, after you turn on the switch, the speaker will work and produce sound, but as long as the lines on the PCB circuit board are broken, the speaker will not work properly because they are all interdependent. Therefore, even though the circuit board is designed to be curved and curved, it seems that there is no regularity, but in fact there is great wisdom in it.
