I recently designed my first 2 PCBs. Both have a 5v copper plane on the top layer and a ground plane on the bottom layer. I use short traces and vias to connect top components to the ground plane.
As you can see in my image, the bottom PCB was manufactured as expected. The top PCB was not. The vias in the top PCB have rings around them where there is no copper (thermal relief?) which means nothing connects to ground and my board does not work.
I designed these using EasyEDA and have viewed them in Eagle. I don't see any difference in my two designs, even though they came out differently.
Is there a term for the vias seen in my top board ( the ones that don't connect)? I obviously need to order these again, but I'm not 100% sure I won't get the same faulty vias.
