Hello All,
As PCB is an important part in Electrical and Electronics system.
We should share our experiences in PCB design.

Can we share what rules should be taken care while designing PCB in Power applications?

One of the biggest mistake is to assume that a track has zero impedance whereas you need to consider the impedance across the fullbandwidth of the currents being carried.
Modern processors and switching devices operate very quickly so you need to have a low impedance up inot MHz.
Ground planes and power planes are much better than ground and power tracks.

Second, consider common current paths. Due to the impedances, common current paths cause cross talk and can result in EMC issues and erratic circuit operation.
Best regards,
Mark.
