The reason for the bending of the circuit inside the 开云·kaiyun官方网站

Printed circuit boards, also known as printed circuit boards, are providers of electrICal connections for electronIC components.

printed circuit board is usually represented by "开云·kaiyun官方网站", not "开云·kaiyun官方网站".

开云·kaiyun官方网站 design is mainly layout design; The main advantage of using circuit board is to greatly reduce wiring and assembly errors, and improve the automation level and production labor rate.

printed circuit board can be divided into single panel, double panel, four layer board, Six layer board and other multi-layer circuit boards according to the number of circuit board layers.

As 开云·kaiyun官方网站 is not a general terminal product, the definition of its name is slightly confused. For example, the motherboard for personal computers is calLED the motherboard, but not the circuit board. Although there are circuit boards in the motherboard, they are not the same. Therefore, when evaluating the industry, they cannot be said to be the same. Another example: because there are integrated circuit parts loaded on the circuit board, the news media call it IC board, but in fact it is not the same as printed circuit board. The printed circuit board we usually refer to the bare board - that is, the circuit board without upper element devices.

multi-layer circuit boards

With the rapid development of modern technology, life is increasingly inseparable from a variety of electronic products. Some friends like to take some old electronic products apart and find that the circuit boards in electronic products are complex. Why do the lines in the circuit board bend? We all have the shortest straight line between two points. Can't the circuit board be designed as a straight line?

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 this era of pursuing delicacy and compactness, the SMAller the area of the circuit board, the better, or 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, it is better that everything else is smaller and smaller, and the thinner the thickness is, the better.

Secondly, even if we do not care about the size of the circuit board and design the circuit in the circuit board as a straight line, it will also cause other problems. In the circuit board, the circuit must turn. If we design the circuit in the circuit board as a straight line, the turning angle will reach 90 degrees. Because it is easy to generate a large reflection when the circuit turns 90 degrees, such a circuit board can be easily broken in the production process. In this way, it will not only cause waste of materials, but also easily cause quality problems even if the circuit board is successfully manufactured.

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

Each zigzag line 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 mutual interference between signals, making our electronic equipment unable to work normally. If the signal of our mobile phone is disturbed, it is likely that there is a problem with the circuit board, and such a mobile phone can almost be scrapped.

The circuit board is composed of devices, capacitors, diodes and so on, which constitute a complete circuit. If you are using a horn, after you turn on the switch, the horn will work and make a sound, but as long as the lines on the circuit board are broken, the horn will not work properly, because they are interdependent. Therefore, although the circuit of the circuit board is designed in a zigzag way, it seems that there is no rule, there is great wisdom in it. Undertake the fast board and fast sample of various 开云·kaiyun官方网站, FPC, 开云·kaiyun官方网站A, soft and hard combination boards, and the medium and small batch production of various electronic finished/sEMI-finished products. 开云·kaiyun官方网站 manufacturers, 开云·kaiyun官方网站 designers and 开云·kaiyun官方网站A manufacturers will explain the reasons for the bending of the circuit inside the 开云·kaiyun官方网站.
