Ruined Board?

[VanWhy]

Did I ruin this PCB? It's an Effects Layouts board and when I break apart the dumb daughter board there was a chunk left on so I cut it a little. But the little turned into more than I hoped. I tried contacting them but it's near impossible to do so. Do you guys think it cut a trace by the pic? I'm think yes but fingers crossed.

I don’t see a trace down there, just ground plane.

On the main board or daughter?

I'd be surprised if it didn't still work fine. You could always do a continuity test between the various points on the board to make sure no traces were cut, just in case.

Both. I think you're fine. If you're not 1000% sure try to trace the board from the schematic and test continuity. I know it sounds annoying, but it's a good skill to have when troubleshooting

Good points. I can always use the practice looking at schematics so I think I'll do some continuity tests on it. Thanks for the responses!

Trace going somewhere from solderpad #3 looks broken (around solderpad 8). I don't know if it's open, you have to "beep" it with the DMM.

Might be that those mouse bites were just too far apart causing the bad break. You should be able to work around a broken traces very easily, though.

Here is the back side of the main board. This doesn't look promising.

So I could use a little advice on how to check for continuity in this circuit. Attached is the schematic. Not sure where to start....

Worst case you may have to make the connection yourself with a wire from #3 to wherever that trace goes (can't see from the picture, as it's blurry on the side, but you may be able to follow it just by looking at the board).

Your right, I'm tracing it from the board now and actually getting continuity. Even on the 3rd pad.

 

[VanWhy]

I think I'm good. Just did a continuity test on all the pads and got them to at least beep once. Thanks for all the responses.

Good luck! Show us the finished build when you're all done.

Great to hear. Use needle nose pliers to break those things apart.
