I have a four layer PCB, TOP/VCC/GND/BOTTOM
When I route from Bottom to VCC the via connecting the two has BOTTOM, hole in the ground, VCC, and a little dot connecting to TOP. Why would it even go to top if I'm not routing in it. Also the previous PCB that I am editing has a ton of little dots on the top and bottom where no routing is seen because it either goes from top to vcc or bottom to vcc... Is there a reason for this? Easy to manufacture?
Thanks.
