Surface Mount Outlines

[Bob Sanderson]

I am in the process of creating an AutoCAD library of SMT components. Can
anyone point me to a good source of outline drawings with dimensions
(including pads) that I can use as a reference? Better yet, does anyone
know of a source, preferrably free, of AutoCAD blocks of SMT components?

Thanks in Advance

smt layouts in the free version, just go into the editor and export, or go
by coordinates and manual copy.

Hello Jim,

rip em from a library in a circuit cad program, eagle has a whole lotta
smt layouts in the free version, just go into the editor and export, or
go by coordinates and manual copy.

But I suggest to still verify them against manufacturer data sheets.
Eagle libraries are AFAIK gathered in a voluntary contribution fashion
so there could be inconsistencies. Data sheets almost always contain the
recommended foot prints and then you have a company like TI or National
behind that recommendation.

eagle is a good source, not of neccessity a great one, it'll be accurate
most of the time, and besides, a good source was asked for.

Wrong. Eagle libraries are made by a full-time employee at CadSoft (the
Librarian) who does nothing else but make footprints.

Sorry, but that is not so. Take a look at who the authors are:
