The great thing about a PCB VIA, is that they can span all layers in the board design, or can start and stop at specific layers. This gives you as a designer many more options to create specific PCB’s that fit your needs.
Altium Designer allows you to edit the properties of a Via. You can select a template from a dropdown menu, or use the library to store VIA configurations such as blind, stub, buried, and through VIA’s. With Altium Designer you can be at your most efficient when applying design rules along with whatever board stack up you choose to adopt.
Within Altium Designer, properties you can edit are:
Diameters - Whether they are top-middle-bottom, full stack, or you need to adjust the hole size
Testpoint settings - The location where a test probe can make contact with the PCB to check for correct function of the board
Solder mask expansions - Define whether you need positive or negative expansion value within the Solder Mask Expansion setting
Tenting - Partial and complete tenting of vias can also be achieved by defining an appropriate value for Solder Mask Expansion
