The fields that let you define the via hole parameters are as follows: Y (second field) вЂ“ This is for the Y position of the via center, and the same procedure can be followed as mentioned above. Units setting in the other region of the properties panel in the board mode can decide the default units when they have not been specified. The field value can be added in imperial or metric units and can be changed according to the requirement. You need to change the field value to alter the via position relative to the current origin.

X (first field) вЂ“ this particular field displays the current X position of the via center to the current origin. Propagational delay вЂ“ this field displays the propagation delay, which is the period of time taken for the signal head to move from the sender to the receiver. If the icon is not enabled, the contents can still be edited. After placement, the icon is enabled, indicating that the placed via properties are defined in the library and are not editable anymore. In case a via is placed from a pad library ( *.PvLib), it will include the library name in the specified field.

Library вЂ“ this displays the via template that is stored in the current library. In case there is a library associated with the template, it is displayed as well. To select another template, the drop-down menu can be used. Template вЂ“ this displays the current template that is used for the via. All vias implemented on the board must be from the via spans defined in the layer stack. This displays every via span thatвЂ™s defined in the layer stack. Name вЂ“ when one or more vias are selected, the via name is displayed by clicking the drop-down. Here you can choose the required net in the design workspace by typing the net name. In case there is no net, click the assign net button to open the dialog for the net name. Every net for the board design that is active will be displayed in the drop-down list. Net вЂ“ utilize the drop-down list to choose the net that contains the via. 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 workspaceвЂ™s top-right part.

Pre-placement settings вЂ“ 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 вЂ“ this via goes between two inner layers of the circuit board.

Blind via вЂ“ 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 вЂ“ 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. 9 How do you set via design rules in Altium Designer? Via overviewДЄ via connects different layers in the PCB and is composed of a barrel, pad, and annular ring.
