I'm doing a PCB in Altium and I don't know what these white rectangles beside my vias are meant to indicate. A screen shot is below:

Vias with the white symgol that I don't understand

  • \$\begingroup\$ What version of Altium are you using? Haven't seen those symbols before. My guess is that they are symbols to show that the two vias aren't connected.. \$\endgroup\$ – m.Alin Feb 5 '15 at 8:50

Since those are vias, what if those symbols were section views of the PCB showing 2 vias which go from the top/bottom to inner layer and stop there? I would guess it means those vias are not through hole; by any chance is it the case?

  • \$\begingroup\$ I think you're right. The vias go from the bottom layer to an internal layer (blind vias). I tried creating a new via and it started showing the same thing as soon as I changed it from going from the top layer to the bottom layer to going from the top layer to one of the internal layers. Thanks a lot! \$\endgroup\$ – Danny Feb 6 '15 at 0:21

I use Eagle, not Altium, so this is an educated shot-in-the-dark. Are those possibly really tiny labels/values/names being rendered as solids because of the zoom?

Try selecting the via, then view all the associated properties. There may be an insignificant parameter that has its Visible option button checked.
