Issue with copper area around a pad

@paulvdh

adding a few pF on 10mm of track is negligible.

I won’t persist. Probably you are right.

@paulvdh

As far as I know, the thing to optimize here is the open area between the tracks, because this creates a magnetic stray field. It acts as a loop antenna.

Do you remember the following discussion:

DC to DC converter

Hello This project is my first to utilize or at least trying to use a proper PCB New to kicad and new to PCB design stuff I like to get some advice in it and about below layout I am not too sure about via placement that I am particularly confused [Screenshot 2023-09-24 222056] Edit.…… This is the final design that I have sending for fabrication Thanks Everyone for kind help And I got decent hang of kicad in the process I added all project file to zip step_up_MT3608L.zip (71…

and information written by BobZ who spend his live designing DCDC?

I learned then that part of loop containing L is not critical to be minimized and worried about. It is because current in L changes slowly (triangle shape without jumps). Critical are parts of current loops where current has jumps.
