Honglian Circuit will interpret the three main points of PCB circuit board design for you! For PCB design novices, there are some design points that need special attention. If you don't pay attention, the designed PCB will probably not be put into use. Today, Honglian editor will explain to you the three must-know points in PCB circuit board design.

First, it is equal length. When designing the differential line, pay attention to making the two signal lines the same length. Because the length of the signal line is the same, the transmission time of the signal is also the same, so the polarity of the differential signal will be different, resulting in the opposite situation. If the differential signals are the same, the signal quality will be poor.

Next, it is equidistant. In other words, the distance between pairs of differential lines must be consistent. By adjusting the distance of the differential line, we can adjust a differential impedance throughout the process. What are the benefits of doing so? If our differential impedance can maintain a certain degree of continuity, there will be little reflection and the transmitted signal will be very complete.

Finally, it is the stacking of differential lines and printed boards. It is generally believed that the differential line will provide a return path for the printed board, and the printed board will use this method to reflow through the differential line, so pay attention to stacking the differential line and the printed board during design.

When designing a PCB circuit board, only by memorizing the above three points can the probability of error be greatly reduced, and the design quality and use value of the PCB circuit board can be continuously improved, so as to truly output high-quality products for customers.
