All components on a Printed Circuit Board (PCB) layout will have a footprint. A footprint is where your component gets soldered on the PCB. These footprints need to be extremely accurate so that your PCB can be properly assembled at the time of manufacturing. Allegro ECAD-MCAD Library Creator can create the most accurate and industry compliant footprints you could want.
Usually, you might need to create your own custom footprints because you cannot always rely on your design tool to provide accurate footprints. Sometimes, you may also need to create a footprint using an existing package or a vendor-provided STEP Model. Library Creator allows you to do all of this. In my previous blog posts about creating footprints, I have already discussed different methods to create footprints. Today, let us discuss all these methods in brief and refresh our memory.
The easiest and simplest method of creating a footprint is using an existing template. In this method, you just:
This is an easy five-step process. To create a footprint using a package, you just:
This method of footprint creation using a vendor-provided STEP Model helps in easily integrating a mechanical and electrical design. This method involves the following steps:
This method of creating a custom footprint is a very commonly used method and helps you when creating a new project and your client demands a new component for which you do not have a footprint. To create a custom footprint, do the following:
Allegro ECAD-MCAD Library Creator allows you to create custom footprints, create component footprints if you already have a STEP Model, and also create footprints using templates and packages. Also, you would want to ensure that everything is transferred to PCB Editor correctly. For this, you can verify the footprints by loading the package in PCB Editor's 3D Canvas.
