Maybe it’s a deficiency on my side, but I can’t remember the whole history of all threads I read, and I’m also not going to re-read the whole thread. Instead I just listed both options (clearance and track width) in my answer and hope OP learns something from it.
It’s OK to use translator tools, but standardized jargon for technical terms is useful and I do expect users to adopt to this after a while, regardless of whether a translator tool is used or not.
I’m sorry for getting emotional.
Even if I search the Internet, ask chatgpt, or ask questions on question sites, it’s impossible to determine the appropriate distance for the circuit, in my experience. I’ll make this question my homework for the future. Thank you, everyone.
I think you should speak with someone in your language to make it more clear.
Clearance can be forced by applying some standard that you are forced to apply by your government rules and standards are very complicated to understand which requirements need be applied where and why.
If not forced you can use any clearance you want until you are sure your circuit will work correct.
