Snapping – select directly or use the Shift+E shortcut to select whether you want to snap to objects on:.A dynamic alignment guideline is displayed when alignment is achieved from the current cursor location to the axially-aligned object snap point (hotspot). The Axis Snap Range defines the distance within which X or Y axial alignment will occur. Axes – used to toggle whether the cursor will axially align (in either the X or Y direction) to the enabled Objects for snapping.A Snap Guide will override the Snap Grid. Guides – used to toggle whether the cursor will snap to manually placed linear or point Snap Guides.The active snap grid is displayed on the Status bar, and in the PCB editor Heads Up display ( Shift+H shortcut to toggle on/off).

When this option is enabled the cursor will pull, or snap, to the nearest snap grid location. Grids – used to toggle whether the cursor will snap to the active design space grid.When you place the footprint on a PCB, all objects that make up the footprint will be assigned to their defined layers. Layer-specific attributes, such as surface mount pads and solder mask definitions, are automatically transferred to appropriate bottom-side layers when you flip the footprint to the other side of the board during component placement.ĭesign objects can be placed on any layer, however, the outline is normally created on the Top Overlay (silkscreen) layer and the pads on the multi-layer (for thru-hole component pins) or the top signal layer (for surface mount component pins). Creating PCB Component Footprintsįootprints are always built on the top side, regardless of which final side of the board they are placed, using the same set of tools and design objects available in the PCB editor. 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 footprint editor using the same set of primitive objects available in the PCB editor. Position and Routing the Jumpers on the PCBĮven with a rich set of resources providing ready-made PCB components (such as the Manufacturer Part Search panel), it is likely that at some point in your career you will need to create a custom PCB component.Suggested Workflow for Working with Jumpers.Footprints With Multiple Pads Connected to the Same Pin.Managing Components With Routing Primitives.Handling Special Layer-specific Requirements.Additional Designator and Comment Strings.Parameters via an Engineering Change Order.Creating a Free-Form Solder Paste Stencil.Handling Special Solder Mask Requirements.Creating a Footprint Using the Footprint Wizard.Creating a Footprint Using the IPC Compliant Footprint Wizard.
