Amateur Needs Some Help With Manuf Rule Violations

#1 Post by SigSoundRich » 27 Oct 2024, 20:58

Hi Folks,

FIRST - to be clear though I am a EE, I am a total amateur at using DIP trace and designing/making circuit board boards and in making/designing circuit boards. Ideally what I would like to find is someone in the upstate central New York (Syracuse) area who can show/tutor me on some things with DIP trace and modern day circuit board design. Or maybe someone I can email my PCB design to and how I can correct them as I have spent some hours trying to fix them with no luck. I *think* I understand what the problems are, but just can't seem to figure out how to correct them. Video tutorials for this that I find/saw are mostly geared at folks like you who are already board design professionals or have some adjacent experience - have not been of help for me.

I have a VERY simple circuit board I have designed/layed out in dip trace, but my complete lack of any expertise in modern day circuit board design is hurting me and preventing me from making the step to finally order a small batch of boards I need made (if you are curious to know its a simple board that would have a volume control and balance control mounted to it for a no longer manufactured two channel vacuum tube high end audio preamplifier)

Thanks - Rich

Negative gap between a pad and copper pour means short circuit. Try update the copper pour for a start. If that doesn't help then more investigation is needed.
Negative gap between silk to pad is less critical but ideally it should be resolved too.
If you share your PCB file and I can say more.

Hmm I don't see any shorts where the SW outlines them (Red circles) - they do tend to be near pads which I have (intentionally) connected to the pour on the bottom of the board (which is basically the ground plane for each channel). I will upload/share the PCB (which I hope no one laughs at - this is something pretty simple compared to the kind of things I imagine are done with the SW)
