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?
