I have a 4 layer board where the GND and power plane are the middle two layers. As you can see from the example below I have a track going from the top to the bottom via a via. The bottom track is shown with an X. The two pink arrows are where I have measured that point to GND and there is a short!
When I have checked over the Gerbers I see this, the blue plane is my GND plane and the Green dots are the via. The via goes stright to ground! There is no relief around it …
This happens at random places on the board … What is going on?
