![]() ![]() ![]() In my experience, it's much more common for PCB footprints to have some kind of problem rather than schematic symbols. Whenever you start a new project and jump into a layout, schematic symbols and PCB footprints need to be correct before a single design document is created. PCB Footprint ProblemsĮvery component that will appear on a circuit board layout will have a PCB footprint. Don't get caught off-guard by incorrect footprints, use our PCB footprint checklist to help you avoid problems and create a smooth design workflow. If a footprint is incorrect, you might get partially through a fabrication run before anyone notices there are problems with your board. Courtyard areas, component designators, and more are encoded in your component model and will appear directly on the PCB layout once you place a footprint. There's more that goes into your PCB footprint checklist than the locations of pads on your components. Because portions of your footprints become part of the stencil used for resist exposure and etching, they need to be extremely accurate, right down to the solder mask exposure and pad pitch. PCB footprints show where your components need to sit in your PCB layout, and they become part of the production files you'll send off to your manufacturer once you start production. ![]()
