Post-placement settings – each via object property can edited in the via dialog and properties panel when a placed via is chosen in the workspace.Īlso read, How to Export Gerber and Production Files in Altium Designer Defining the via parameters.The next step is to select the via object in the list of primitives to display the options on the right. This is available on the defaults page of the preferences dialog that can be retrieved through the button at the workspace’s top-right part. Pre-placement settings – object properties for a via that can be logically defined beforehand are accessible as editable default settings on the PCB Editor.The property settings for every object type can be measured in two distinct ways: PCB Editor object properties are options that are used to define the visual style, content, and behavior of the placed object. In the next sections, we will discuss the method in which the pad, hole sizes, and types of vias are defined and designed. This may be a power, ground, or signal name. When the via is imported into the board it is assigned to a signal/net. Buried via – this via goes between two inner layers of the circuit board.Blind via – this type of via goes from either the top layer or bottom layer to the layer immediately next to it, and does not travel through the whole board.Through-hole via – this via goes from the top layer to the bottom layer of the board.

The different types of vias are as follows: Therefore while designing the via, the pad sizes and hole sizes are defined. A typical through-hole via will have pads on the top layer, bottom layer, inner layers, and the hole that goes through the pad. In this article, we will go over the fundamentals of via design using Altium Designer electronic design automation software.Ī via connects different layers in the PCB and is composed of a barrel, pad, and annular ring.

With the advent of surface mount technology, blind and buried vias were introduced, calling for complex via design practices. The early days of PCB fabrication saw the exclusive use of through-hole vias that span the complete thickness of the board.
