With the rapid development of modern science and technology, our life is increasingly inseparable from a variety of electronic products. Many curious friends like to take apart some old or bad electronic products. At this time, we will find that these electronic products will have some circuit boards (circuit boards), but the circuit boards inside these circuit boards are too complex, right? Why does the circuit inside the circuit board bend and bend so that ordinary people can not understand it? Can't circuit boards be designed as straight lines? You may not believe it.
After we studied mathematics in junior high school, we knew that the line between two points was the shortest. So why are circuit boards designed to be curved? First of all, if the circuit in the circuit board is designed as a straight line, the area of the circuit board will increase several times. In today's era of pursuing delicacy and compactness, the smaller the circuit board area is, the better, 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 screen, other things are getting smaller and smaller, and the thinner the better.
Secondly, even if we do not consider the size of the circuit board, the PCB line design into a straight line, it will also cause other problems. In circuit boards, the circuit must be turned. If we design the circuit in the circuit board as a straight line, the turning angle will reach 90 degrees. Because the circuit can easily produce a large reflection when turning at 90 degrees, such circuit boards can easily be broken in the process of production. In this way, not only waste material, even if the circuit board is successfully manufactured, it is also easy to produce quality problems.
Thirdly, the circuit on the circuit board is designed to bend in order to ensure the stability of the signal. The design of circuit board is a kind of technical activity. Only by adopting corresponding design can the stability of signal be ensured. Only when the signal is not disturbed can the chip on the circuit board work properly.
Each curved circuit on the circuit board represents a different signal. If the circuit on the circuit board is designed as a straight line, it is easy to cause interference between signals, so that our electronic equipment can not work properly. If the signal of our mobile phone is disturbed, it is likely that there is a problem with the circuit board, then such a mobile phone can almost be declared scrapped.
Circuit boards are constructed by devices, capacitors, diodes and so on. These many lines constitute a complete circuit. If you use a speaker, when you turn on the switch, the speaker will work and make a sound, but as long as the lines on the circuit board are broken, the speaker will not work properly because they are interdependent. So, despite the fact that circuit boards are designed to bend and bend as if they were irregular, they actually have great wisdom in them. Do you dare to disassemble the electronic equipment after reading it?
