Along with Track objects, Pads and Vias are fundamental elements of all circuit board designs. To raise the design reuse and management capabilities for Pads and Vias in PCB designs, Altium Designer supports Pad and Via template Libraries. The concept of Pad and Via templates that can be collected in a Library is not unlike that of PCB footprint libraries, although somewhat more basic. The Pad…

The Role of the Via Vias are used to create the vertical, or layer-to-layer connections in a printed circuit board. In the early days of board fabrication, all of the vias passed all the way through the board, from one side to the other. These thru-hole vias are drilled after the layers are fabricated and the routing etched. The conductive via barrels are formed in the drilled holes using an…

Along with Track objects, Pads and Vias are fundamental elements of all circuit board designs. Each Pad and Via can be configured as a custom object during or after placement. Pad and Via in 3D To raise the design reuse and management capabilities for Pads and Vias in PCB designs, Altium Designer also supports: automated Pad and Via template creation; Pad and Via template Libraries; and a number…

Parent page: PCB Placement & Editing Techniques Pad and Via Summary Pads are used to provide both mechanical mounting and electrical connections to the component pins A pad is a primitive design object. Pads are used for fixing the component to the board and for creating the interconnection points from the component pins to the routing on the board. Pads can exist on a single layer, for example,…

Parent page: Working with Pads & Vias Working with Custom Pad Shapes The standard pad object can: Be set to a number of different shapes, including round, rectangular, rounded rectangular, and octagonal. Be sized differently in the X and Y directions, extending the range of shapes that can be created. Be customized to change the shape for each layer of the board. Have a round or slotted hole,…
