Hi Ray,

The spec for surface mount footprints is IPC-782A with amendments 1 and 2. Since you are in Government, you probably have a copy available in your command library. If not, standards are for sale through www.ipc.org

Hello,

I'm sure this is a repeat, but is there a simple specification readily available that gives the "commonly accepted" (if there is such a thing) dimensions for 0402, 0603, ..., SIOC-14, etc., and all the other "standard" footprints? I don't really want to wade through a bunch of technical stuff to derive all of this myself and I certainly don't want to trust a priori the patterns that come with Protel or any other product. It's really annoying when part manufacturers don't provide these footprints, assuming they are common knowledge.

Thanks,
Ray Mitchell
