At Vnisource, we believe all designs start at the component level. The key to being efficient for every PCB Designer is the library you work from. The more intelligence that is built into a library, the faster you can accomplish in a given amount of time. The fewer components you have to build or maintain. We have developed a set of PCB footprint libraries that will help you work more efficiently.

We have several libraries for several ECAD tools available. Each library set has approximately 25,000+ and most up to date library available anywhere. We apply IPC and JEDEC industry standards to create the most consistent, accurate, and complete EDA-compliant design elements for several CAD tools. Features of our libraries include:

• Over 25,000+ unique footprints available
• IPC-SM-782 Three tiers - Nominal, Least, Maximum
• All footprints have attributes such as: courtyards, polarity marking, assembly inspection dots, geometry height, full padstacks and more
• Footprint origin is located at pin #1 for thru hole components and at the center of the body for SMT components
• All footprints are properly dimensioned in a layer that can be turn OFF or ON for checking
• All footprints have seperate reference designator 'REF-DES' on silkscreen layer and one on assembly layer

• Altium/Accel P-CAD 200X Libraries
• Cadence Allegro Libraries
• PADS PowerPCB Libraries
• Cadence Orcad Libraries
