Re: gEDA-user: IPC standard SMT footprints (0603, 0402 vs. RESC0603N etc.)

[Geoff Swan <shinobi.jack@xxxxxxxxx>]

        01005 (0402 metric) : 0.016" × 0.008" (0.4 mm × 0.2 mm)
        0201 (0603 metric) : 0.024" × 0.012" (0.6 mm × 0.3 mm)
        0402 (1005 metric) : 0.04" × 0.02" (1.0 mm × 0.5 mm)
        0603 (1608 metric) : 0.063" × 0.031" (1.6 mm × 0.8 mm)
        0805 (2013 metric) : 0.08" × 0.05" (2.0 mm × 1.25 mm)
        1206 (3216 metric) : 0.126" × 0.063" (3.2 mm × 1.6 mm)

   This is a timely thread... I am in the process of finalizing my first
   serious gEDA pcb and building a small library of heavy symbols... I
   don't think I've double checked if I have 0603-metric or 0603-imperial
   footprints :P
   This also highlights why in many respects - regardless of the source I
   prefer to double-check all footprints...
   For myself I think I'll start naming the footprints with a metric or
   imperial tag of some description... M0603.fp and P0603.fp or
   something... (P for imPerial)
