Direction for placement on pcb

[Frederico Acardi]

Hi. I need your advice on something useless but lets see.
What would you do and why?
I am intentionally not giving any more info to keep the discussion open.
Thank you.

An externally hosted image should be here but it was not working when we last tested it.

This depends on the impedances and voltage levels. You have to be specific.

 

[Frederico Acardi]

That is exactly what I want. I want it to be like that. Lets see where it leads
Thank you rayma.

It depends. I agree with previous orator.

Ok, I can tell a little much: resistors can't be by their own without other circuit. So it may be easier to connect them as first figure or as the second.

It doesn't matter. If you want to have the wires come and go from opposite sides of the board, do it one way. If you want both wires on the same side of the board, do it the other.

This is an audio forum,l so I am not even considering esoteric RF situations.

If my voltages are so high I have to worry about arcs between the two parts, then space them farther apart.

If you are looking for really unusual circumstances where placement might make some tiny difference, someone else can follow that fish.

The left layout has less inductance, and less loop area for noise pickup.

The right layout is better for stuffing directional components (diodes, etc.).

I wouldn't do either if I could avoid it, I would place them inline and as close together as thermal considerations would permit. I would also ditch the leaded parts in most cases even for high voltage use.

Is it part of the test, to see what assumptions each poster applies? I mean is it a pair of rectifiers for a relay supply? A pair of rectifiers for a B+ supply? A pair of resistors in a voltage divider in a signal chain? (Like a cheap divider across a speaker to make a line out). Two caps in series for voltage reasons? Part of a hum balance for AC heaters?

COntexts matter, so inductance that matters in a UHF receiver won't matter a whit in a relay supply. Sensitivity to picked up noise would be about zero in a heater hum balance.

And so on.

Excactly but as a non native speaker I did not know how to word it.
