Why are the lines on the circuit board crooked

With the rapid development of modern science and technology, our lives are increasingly inseparable from a variety of electronic products. Many curious friends like to take apart some old or broken electronic products. At this time, we will find that these electronic products will have some circuit boards, but the circuits in these circuit boards are too complicated, right? Why is the circuit inside the circuit board twisted and twisted so that ordinary people can't understand it at all? Can't the circuit board circuit be designed as a straight line? You may not believe it. Let's take a look at the editor from Shenzhen PCB Manufacturers!

First of all, we all know that today's electronic products are as small as possible, and as fine as possible. This design must have strict restrictions and requirements on the wiring of the circuit board, so that so many electronic components can be installed. If it is designed in a straight line, it will definitely lead to an increase in the area of the circuit board. As a result, it does not conform to the lightweight and compact design. It seems that every route is a disorderly sequence, but in fact every route has undergone careful calculations. Every component on the circuit board must have strict requirements if it wants to ensure normal operation. If the specific circuit is not followed,

Secondly, even if we don't care about the size of the circuit board and design the lines in the circuit board as a straight line, 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 prone to large reflections when turning at a 90-degree turn, such a circuit board can easily 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.

So this is also to ensure the integrity of the signal, which the designer should take into consideration when designing. Different parts are distributed on a circuit board, there are various power sources, various capacitors, resistors and so on. When each part is combined together, it will interfere with each other, so this must be taken into consideration when designing. With this kind of curved wiring, the signal delay difference between the various parts will be kept within a range, so that it will not cause confusion when reading. If it is a bad wiring, it will not only reduce the performance of the product, but sometimes even affect the success rate of the product, so regardless of a small wiring, there are still a lot of content involved.

So, don't look at the circuit board's circuit is designed to bend and curve as if it is irregular, but in fact there is great wisdom in it. After reading it, do you dare to disassemble the electronic equipment casually?
