Why the lines on PCB must be bent?

Jul 24, 2018

With the development of the times, electronic products are increasingly inseparable from our lives, from computers to mobile phones. However, electronic products always face a problem, that is, they are broken. This is inevitable for electronic products, after all, electronic products have a long life.

Speaking of whether everyone has ever dismantled electronic products?  People are curious and want to know what is hidden inside!


Do you know why the lines on PCB must be bent


First of all. We all know that the current electronic products are as small as possible, the finer the better. This design must have strict restrictions and requirements on the wiring of the board, so that you can install as many electronic components.

If you design a straight line, it will definitely lead to an increase in the area of the board, which is not a lightweight and compact design. It seems that each line is a disorderly sort, but in reality every line has undergone meticulous calculations.

Every component on the board needs to have strict requirements to ensure normal operation. Once it is not in accordance with a specific line, it will inevitably lead to data errors.


Secondly, in order to ensure the integrity of the signal, designers should consider it when designing. Different parts are distributed on one circuit board, and there are various power sources, various capacitors, resistors, and the like.

When each part is combined, it will cause mutual interference, so it must be taken into account when designing. With this curved wiring, the signal delay difference between the parts is kept within a range, so that the reading is not disturbed.

If it is a bad layout, not only degrades performance products, and sometimes even affect the success rate of the product, So don't look at it is a small wiring, the content involved is still a lot.
