In a project I'm working on, I have an odd setup. I'm sending low frequency analog waveforms to a device. Now this device has two sets of pins on opposite sides that need to be externally connected. By low frequency, I mean really slow (10-20Hz).
Is there some sort of rule-of-thumb for the allowable difference in trace lengths dependent on frequency? I can meander / trombone / snake the traces but at a higher voltage that I'm working with (150V), I'm thinking that it might cause more RF issues than it would solve... The delta I'm looking at would be on the order of 600mils. It's a lot, but given the wavelength of 20Hz, even at half the speed of light, is on the order of thousands of kilometers. It seems like the delta in my case would be a negligible percentage even in a desired low-noise setup like I'm working with.
If I were to meander / trombone / snake the traces to get everything to match, the general consensus for that would be to make sure that there is proper isolation per the voltage (16mils) between the traces and that there is no ground plane between the arcs?
