Vendor Neutral File (VNF) Standards Typically our Vendor Neutral Files are designed to contain both the size of the component (when dealing with footprints) and the size of the pads and other information required to create an appropriate footprint.  By default we use the IPC-7351 standard for building our footprints, with a few minor variations. Your customers however will have a variety of standards that they support or require.  One advantage of our VNF is that for those customers that have a need for libraries that meet a standard different from what you are providing them, they have a path that still allows them to benefit from the download you make available. Since our VNF contains the size of the part, as well as the calculated footprint, we are able, in our purchased tool, to recreate the footprint based on the downloaded size of the part.  The recreation process, and what calculations are required to add, delete or modify entities in the footprint are all designed to be controlled by the user.  This process would REQUIRE the user to purchase our tool set, but would still allow them to download valuable time saving data from your site. Additionally your company may prefer to provide your components built to a specification different from the IPC.  This can be accommodated as we create the VNF by simply modifying the templates or family instructions we use in building libraries.  Thus even if we already have the packages you use built (for instance the JEDEC standard packages), we can modify the footprints that are in the VNF to meet your company standard rather than the IPC calculations on how to build the footprints.  This can then be exported to your customers in the same format. Symbol creation is similar to footprints.  Almost all of our symbols are built as a standard "box" symbol unless we are building discrete or connector style parts.  However both your customer and your company can modify the standards that the symbols are built to, since the real critical data about the symbol is stored in the VNF as both a set of parametrics (that drive a template) as well as a set of graphical descriptions that would be sent to a CAD tool.
