Note that rules are defined in the PCB editor, during board design. While mask settings can be defined manually for each pad doing this makes it difficult to modify these settings later during the board design process, typically this is only done when it is not possible to target the pads by design rules.
Pad-specific attributes, such as solder mask and paste mask are automatically calculated based on the pad dimensions and applicable mask design rules. To check a distance between two points in the workspace, use the Reports » Measure Distance command which is also available through the Ctrl+M shortcut keys. Alternatively, double-click to edit a placed pad and enter the required X and Y locations directly in the Pad dialog. Use the Shift+H shortcut to toggle the Heads Up display on and off. The Heads Up display contains both the location and the delta from the last click location to the current cursor location. The current X, Y location is displayed on the Status bar, and also in the Heads Up display. Additionally, holding Shift will move in steps of 10 times the grid. To accurately place a pad while moving it with the mouse, use the keyboard arrow keys to move the cursor in current grid increments. Use the Ctrl+G shortcut keys to open the Grid Editor dialog and the Q key to change the grid from Imperial to Metric or vice versa. To ensure accurate placement of the pads, consider setting up a grid specifically for the task. Some care should be exercised when designating pads as it is this property that Altium Designer uses when mapping from pin numbers on the Schematic Symbol. For a thru-hole pad, set the Layer to Multi-layer. For a surface mount pad, set the Layer to Top Layer. The designator automatically increments for subsequent pad placements. After running the place Pad command but prior to placing the first pad, press the Tab key to open the Paddialog and define all the pad properties, including the pad Designator, Size and Shape, Layer, and Hole Size (for a thru-hole pad). Place the pads ( Place » Pad) according to the component requirements. If you've forgotten to move to the reference point before beginning to build your footprint, you can bring the reference pad to your footprint using the Edit » Set Reference sub-menu commands. Use the J, R shortcut keys to jump directly to the reference point. Footprints should be built around the workspace reference point at the center of the PCBLIB editor. The typical sequence for manually creating a component footprint is: The pads and component overlay can be seen below the STEP model. The 3D image shows the imported STEP model for the component, note placed directly from the Altium Content Vault, a globally accessible component storage system that contains thousands of components, each with a symbol, footprint, component parameters and links to suppliers.ĢD and 3D views of a footprint for a joystick component. created in and placed from local libraries, or. The real-world component that gets mounted on the board is represented as a schematic symbol during design capture, and as a PCB footprint for board design. In addition to footprints, company logos, fabrication definitions and other objects required during board design can also be saved as PCB Components. PCB Component Footprints are created in the PCB Library editor using the same set of primitive objects available in the PCB editor. However, even with this rich set of resources, it is likely that at some point in the designer's career they will need to create a custom PCB Component.
