![]() Component – this field is shown in the PCB editor only when the selected Pad is a constituent part of a PCB Component and displays the designator of the parent PCB component.The Pad mode of the Properties panel Properties To move a free pad without moving the connected tracks in the PCB or PCB Library Editor, select the Edit » Move » Move command, then click, hold, and move the pad.The connected routing will remain attached to the pad as it is moved. To move a free pad and also move the connected tracks, click, hold and move the pad.Pads and vias cannot have their properties modified graphically other than their location. The shape of the pad will be set to Round. The via's diameter size is used for the pad's XY sizing on the applicable layers. Select all vias that you wish to convert in the design space and choose the Tools » Convert » Convert Selected Vias to Free Pads command from the main menus. The vias will be converted to free pads of the same style ( Simple, Top-Middle-Bottom, or Full Stack) and with the same hole size. This allows proper connection to internal power planes, using editable pads. Changing vias to free pads can be useful when importing PADS-PCB and PADS 2000 files, where vias are used to connect to power and ground layers. The highest value found across all available XY size pairs for the pad (corresponding to the pad size on different layers) will be used for the via's diameter.Īlso, vias can be changed into free pads. Changing free pads to vias can be useful when manually converting imported Gerber files back into PCB format. Select all free pads that you wish to convert in the design space and choose the Tools » Convert » Convert Selected Free Pads to Vias command from the main menus. The free pads will be converted to vias with the same hole size. The key difference between a via and a pad is that as well as being able to span all layers of the board (top to bottom), a via can also span from a surface layer to an internal layer or between two internal layers.įree pads on the Multi-layer layer can be changed into vias. A free pad is one that is not part of a parent component object. In the X and Y planes, vias are circular, like round pads. The barrel-shaped body of the via is formed when the board is drilled and through-plated during fabrication. Vias are three-dimensional objects and have a barrel-shaped body in the Z-plane (vertical) with a flat ring on each (horizontal) copper layer. Vias are used to form a vertical electrical connection between two or more electrical layers of a PCB. Pads can be used individually as free pads in a design, or more typically, they are used in the PCB Library editor, where they are incorporated with other primitives into component footprints.Ī via that spans and connects from the top layer (red) to the bottom layer (blue), and also connects to one internal power plane (green).Ī via is a primitive design object. In the X and Y planes, pads can have a round, rectangular, octagonal, rounded rectangular, chamfered rectangle, or custom shape. The barrel-shaped body of the pad is formed when the board is drilled and through-plated during fabrication. Pads can exist on a single layer, for example, as a Surface Mount Device pad, or they can be a three-dimensional through-hole pad, having a barrel-shaped body in the Z-plane (vertical) with a flat area on each (horizontal) copper layer. 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 are used to provide both mechanical mounting and electrical connections to the component pinsĪ pad is a primitive design object.
