Other situations where you might create a PCB footprint include: This is an example of a time you might have to design your own PCB footprint. ![]() Imagine you are using a component in your circuit, but could not find the component library in the PCB design software database. Sometimes designers have to create their own PCB footprints. Otherwise, they will not fit into the pads. The PCB footprint should match the component in physical dimensions. However, there is a provision to create the PCB footprint by the designer as well. The Various Parts of a PCB Footprintįor all standard components, footprints are available within the PCB design software library. Through traces and vias, the PCB footprints on a board are interconnected. ![]() The PCB is then assembled according to the PCB footprint, also called a land pattern or pad pattern. The PCB footprint gives the designated locations to solder the components as per the design as well as the physical size of the components, placement location, and associated traces. A PCB footprint is the physical interface between a component and the circuit board.
