Before i go to far i want to check that im not doing terrible things or starting of with bad habits when it comes to routing, which is already making my head hurt a bit!
Is it recommended do do things like this when needing to change the order of two traces because its target component wants them the other way around?
I am trying to keep the majority of traces on the top layer where possible so just taking short dips down the bottom layer and back up instead to keep the bottom layer clear for longer runs that might be needed in the locality.
Or is this frowned upon, or there is a better way i haven’t found or though of yet.
I’ve learnt an incredible amount in the last few days and am really appreciating the kind responses im getting to what i imagine are really obvious questions. My degree in electrical engineering was 20 years ago and as a software engineer i havent had to actually use it in anger… ever lol.
Are this 2 nets unrelated to each other? Or is it a differential pair?
If they are independent, i would worry more about crosstalk than the exact form of a crossing. If they are a differential pair, i would route it differently. (You other thread about decoupling capacitor placing is probably less of a worry than crosstalk. But that also depends on a lot of factors you are apparently not willing to tell, like frequency range, types and uses of the signal, …). It of course depends a lot on what signal this nets carry.
In the case of the screenshot, you can just route under the capacitors and resistors to avoid a crossing.
HI @johannespfister , this is an audio signal in this case, right and left speakers.
Why didn’t you say at the start that you do something with Audio.
In this case, it probably doesn’t matter that much and crosstalk shouldn’t be a big issue. The frequency is low. Well, depends on what expectations you have.
And:
C21 can be placed over R24 and its connection will have to go only under R24.
I believe symmetry in positioning is not a very important parameter here.
