Any parts previously built/saved in the Footprint Expert neutral format can be rebuilt to any CAD format, with any modified setting. Default rotation? Change setting, batch-build! New tolerance? Change setting, batch-build! Different pad shapes? Line widths? etc... No problem! Modify the Naming Conventions? done!! Any of these updates, plus many more for your entire library? Just click "Build"!!! Footprint Expert supports 5 Footprint Naming Conventions:
You can test them in the Calculator > Design Options > Footprint and Pad Stack Naming. Example: QFN w/Thermal Pad PCB Libraries (IPC-7351C) = QFN29P50_500X400X80L40X25T355X255 IPC-7351B = QFN50P500X400X80-29 IPC-7352 = QFN50P500X400X80-29T355X255 ------------- Stay connected - follow us! https://twitter.com/PCBLibraries" rel="nofollow - X - http://www.linkedin.com/company/pcb-libraries-inc-/" rel="nofollow - LinkedIn |
