Which method do you know below to reduce noise and electromagnetic interference in PCB design?
This article uses Protel99 SE as a design tool to analyze and discuss the basic principles and experience and skills in PCB design.
Although the high-speed simulation tools and interconnect tools at this stage can help designers solve some of the problems, high-speed PCB design also requires the accumulation of experience and in-depth communication between the industry.
The via design consists of a pad and a pad area around the hole and an inner electrically isolated area. The parasitic inductance, parasitic capacitance, etc. of the vias affect the high-speed signals passing through the vias. The size of the vias and the pads connected to them have a direct effect on the properties of the vias.
