Saifu De Technology Circuit explains the three main points of PCB circuit board design for you! For newcomers to PCB design, some design points need to be especially noticed. If you don't pay attention to it, then the PCB you design will probably not be put into use. Today, Saifu De Technology Xiaobian will come to explain for you, the three major points in the PCB circuit board design.

 

First of all, it is the same length. When designing differential lines, be careful to make the length of the two signal lines as long. Because the lengths of the signal lines are the same, the transmission time of the signals is also the same, so that the polarity of the differential signals will be different, resulting in the opposite situation. If the differential signal is the same, the signal quality will be poor.

 

Then, it is equidistant. In other words, the distance between the differential lines should be the same. By adjusting the distance of the differential line, we can adjust a differential impedance throughout the process. What are the benefits? If our differential impedance is able to maintain a certain degree of continuity, then there will be very little reflection and the transmitted signal will be very complete.

 

Regarding PCB circuit board design, Safford Technology Circuit will explain the three essential points for you.

 

Finally, it is a stack of differential lines and printed boards. It is generally believed that the differential line will provide a reflow path for the printed board, and the printed board will use this way to reflow through the differential line, so care should be taken to stack the differential line and the printed board.

 

When designing the PCB circuit board, only by memorizing these three points, the probability of error can be greatly reduced, the design quality and use value of the PCB circuit board can be continuously improved, and the high quality product can be truly output for the customer.
