When you have a component and you need to create a PCB footprint, Altium Designer’s component creation tools let you create a PCB footprint in the same utility as your schematic symbol. Schematic symbols are needed for circuit diagrams, but a real circuit board layout needs PCB footprints for components. Complete Your Component Libraries with PCB Footprints The Altium Designer Symbol Wizard helps you quickly create a schematic symbol with IC pin numbers and pin names. You can then save your new component data in your libraries and start adding your custom part models to your design. Once you find your datasheets on Octopart, you can manually enter IC pin numbers and pin names in your schematic symbols, such as in the example shown below. A clear silkscreen outline and courtyard outlineĮverything you need for these component creation tasks can be found in Altium Designer.Pin numbers placed on the PCB footprint pads and schematics.Geometrically correct pinout with pad locations and shapes.Every component needs to have some important features that help designers quickly understand and place the component in schematics and a PCB layout: How to Build Components with Accurate IC Pin NumbersĪll ICs have a package outline with electrical leads for making connections to other components on the PCB. Altium Designer gives you these features and many more in an easy-to-use interface. Today’s ECAD vendors have stepped up to solve this long-standing problem with sourcing utilities and CAD tools for creating components. This creates plenty of confusion that PCB designers can’t afford. Sometimes, the pin numbers are done by someone who is inexperienced, or the IC pin numbers have incorrect names. One common problem with component models is getting models with accurate IC pin numbers. No PCB layout will make it off a computer screen and onto a fab line without accurate component models. Have you ever downloaded CAD data for a component from a parts website, only to find that the CAD models were totally wrong? Even worse, have you ever opted not to use a desired component because you couldn’t find CAD models? Even today, when the electronics industry is more digitized than ever, this remains a major problem for PCB designers. The only PCB design package with a complete set of component creation features for your PCB layout.
