Distributed noise caused by the inherent impedance of the power supply. In high-frequency circuits, power supply noise has a greater impact on high-frequency signals. Therefore, a low-noise power supply is required first. A clean ground is as important as a clean power supply; common mode field interference. It refers to the noise between the power … Continued
According to the different manifestations and causes of power supply noise interference analyzed above, the conditions under which it occurs can be targeted, and the interference of power supply noise can be effectively suppressed. The solutions are: Pay attention to the through holes on the board. The vias require etched openings in the power supply … Continued
Under normal PCB design conditions, the following factors are mainly affected by the PCB manufacturing: The thickness of the dielectric layer is proportional to the impedance value. The dielectric constant is inversely proportional to the impedance value. The thickness of copper foil is inversely proportional to the impedance value. The line width is inversely proportional … Continued
When conducting PCB wiring, it often happens that when the trace passes through a certain area, due to the limited wiring space in this area, a thinner line has to be used. After passing through this area, the line returns to its original width. Changes in trace width cause impedance changes and therefore reflections, affecting … Continued
The process of printed circuit board from light board to display circuit graph is a more complex physical and chemical reaction process, this paper analyzes its last step – etching. At present, the typical process of printed circuit board (PCB) processing is “graphic electroplating method”. That is, on the outer layer of the board to … Continued
