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
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
When we design a PCB, we sometimes encounter circuits with higher voltages, so how to take care of the creepage distance when designing, the following discusses this issue. When considering the creepage distance, the relationship between voltage and distance should be considered, as well as other factors, such as humidity, temperature, air composition, pollution condition, … Continued
The development of horizontal electroplating technology is not accidental, but high density, high precision, multi-function, high aspect ratio multilayer printed circuit board products special function needs, is an inevitable result. Its advantage is that it is more advanced than the vertical hanging plating process method now adopted, the product quality is more reliable, can achieve … Continued
PCB Design Basics Printed circuit boards (PCBs) appear in almost every electronic device. If there are electronic parts in a device, they are all mounted on PCBs of various sizes. In addition to fixing various small parts, the main function of the PCB is to provide the mutual electrical connection of the various parts above. … Continued
What is HDI PCB (HDI blind buried via PCB)? Why is there a separate category called HDI in the PCB technology category? HDI is designed to provide a lot of interconnect in a very small space. Components are placed closely on the board, which helps reduce size, but functions like a larger board. HDI PCB … Continued
