PCB layout critique
« on: September 12, 2015, 08:03:05 am »
Hi

I am working on building a guitar graphic eq. Pretty generic filter stages, 30mm slide potentiometers to control gain.

I have never laid one of these eq stages out before. How does this look as a starting point? Any tips would be appreciated. I am self taught, so if I am making any obvious mistakes, please let me know! Not all of the connections are present on the PCB yet, just trying to determine the best layout for the filter components, as it will be duplicated across the PCB.

Thanks!

Maybe use one side of the board as a ground plane and increase the width of your tracks. I like to make all tracks as wide as possible regardless of how little current they are to carry. I also like to have caps as close to the IC they are decoupling as possible.

Hi, Yes, Ground plane is planne for the other sie of the board, coupled with vias from the top at every ground connection.

What is the advantage of larger traces?

Yep, decoupling will be added soon!

Right now, Im really just concerned about the layout of the parts...will it lea to oscillation? etc.

Mainly
 - Less resistance
 - Better thermal performance
 - More robustness
