Circuit Board Layout for EMC: Example 2

[@shomonercy]

Not a board designer really, but this vid opened my eyes to a lot of stuff. Thanks for putting this up!

"Since electric guitar signals are not as sensitive to noise as some other audio signals" is incorrect. Electric guitar signals typically have up to 60dB of gain applied to them to cause them to distort to get the typical overdriven sound. This boosts the noise floor by 60dB effectively taking a microscope to the noise floor. Any digital sounds are completely exposed. Electric guitar signals in my experience are only second to Mic pre amps regarding sensitivity to noise. Mic pre amps with equivalent noise input (EIN) in the 126-129dBu range are the only signal types that are more sensitive in the land of audio design. Still a fantastic video!!! Thanks lots.

Thank you very much! Subbed and waiting for new videos.

thanks for the very useful tips still I think board stack-up is not optimal for EMC since there is no reference plane for signals on layers 1 and 6.

you are awesome.... that is really good stuff you showed in videos.. thank you and keep it up.👍

Very helpful, thank you!

[@ezvisage1553]

wow. Nice. But can i ask you a question? In the layout that you suggest, the closk is replaced to the new place. So, are there any crosstalk possibilities between a clock thace from the oscillator and input/speaker traces? Im not sure about my question, so i have a lot of doubts. Can you explain, please?

[@LearnEMC]

You raise an excellent point. If the clock trace is routed on one of the lower layers and the I/O traces are on the top layer (with the IC), then there will be no measurable crosstalk. If the clock trace is routed directly beneath the IC, there may be enough crosstalk to be a concern.

thank U very much for these examples 1, 2 and 3
