You actually have found the specs or have you paid for them?

(should the 0805 (2012 Metric) be called a 201250 > Metric?) Not only that, there are other technological constraint. Like when you work on 70um copper or you do a board to be conformal-coated, the pads' shapes change a little... > > I found this: http://www.xs4all.nl/~ljh4timm/pcb-fpw/pcb-fpw.html > > It would be cool if someone tweaked pcb-fpw to to produce kicad footprint > libraries.. I could give it a look. I've already done some library generation, kicad format is actually trivial...
