![]() The suffixes 'L' and 'M' indicate Least and Most real estate on the PCB and the name with no suffix indicates Nominal density on the PCB. ![]() ![]() ![]() The footprints available in three sizes (based on the IPC-7351 standard for the Least, Nominal, and Most) follow this naming convention: xxxxxx for Nominal, xxxxxx-L for Least, and xxxxx-M for Most. It is anticipated that this free download service will save TI's customers significant time. Providing components based on parametric data through the Ultra Librarian Reader will allow TI customers to reliably create consistent quality CAD entities to an established standard with minimal effort. In addition, the components (both symbol and footprint) can be modified to meet a user-defined standard using a purchased upgrade to the Ultra Librarian. The UL Reader is a subset of the Ultra Librarian toolset that can generate, import, and export components and their attributes in virtually any EDA CAD/CAE format.įootprints generated by the UL Reader are based on the IPC-7351 specification (with the exception of DSBGA, QFN, and SON packages which have one footprint only). The reader is available for free download ( ZIP: 77MB).
