Standard Footprints

Footprints for common packages used by many different components.

Special Footprints

Footprints for components that don't necessarily use a standardized package or layout.

QFN Footprints

I'm a little intimidated by these little QFN packages. Alas, I've been asked to use a chip that doesn't have any alternative package.

"QFN/SON PCB Attachment Application Report: SLUA271"

"QFN Layout Guidelines: sloa122"

prototyping boards for Chip Scale (QFN) Packages from SchmartBoard

Any other tips?

The Open Symbol Project

"The Open Symbol Project aims to create an open collection of schematic symbols and PCB footprints released under a license that does not interfere with use in either commercial or free projects. ... can easily be modified to accommodate various design rules."

What can we do to help the Open Symbol Project?

Links to Footprints

  • un-tested gEDA symbols and footprints
    • All of these Symbols are heavy symbols. gEDA has already provided most of the above symbols in light format for us to modify. The above symbols include more information than normal to save some time instead of configuring each symbol every time you use them.
