1. Attached is the image of two different vias on two pcb's. Second pcb(green) have vias designed by me in ultiboard, it has a drill & pad diameter as metal layer around each via.
2. First board(blue), has different vias. It dont have any metal/cu on top. What is this type of via?
3. How to create it? Is there any different between two or one ia better than another?
4. These vias are only used for current transfer from one layer to another..
