PCB component footprints are created in the PCB footprint editor using the same set of primitive objects available in the PCB editor. The 3D Body object is used as a container into which a generic MCAD format model can be imported, as shown in the image below.Ī suitable MCAD model can be imported into a 3D Body object.Įven 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. The component that is mounted on that footprint can be modeled using 3D Body objects. The footprint defines the space the component occupies and provides the points of connection from the component pins/pads to the routing on the board. In the example footprint below, most of the component outline is defined on a mechanical layer (the green lines) rather than the (yellow) overlay, because this component will be mounted so that it hangs over a cutout in the board. A typical footprint includes pads and a component overlay, and can also include any other mechanical details required. The area that the component occupies on the fabricated board is defined by the component footprint.
