  • System, PCB, & Package Design : BoardSurfers: Four Ways to Create Footprints in Allegro Library Creator

    Sanjiv Bhatia
    Sanjiv Bhatia

     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…
