Re: gEDA-user: pcb footprint for 100-pin TQFP, with 0.65mm pitch?

[Rick Collins <gnuarm.2007@xxxxxxxxx>]

I haven't looked in the library, but this part should be 
there.  Instead of looking for a TQFP, look for a QFP or a 
PQFP.  This is an old footprint and should be very common.

If all else fails, you can download a footprint dimension library 
from PCB Libraries at http://www.pcblibraries.com/.  The footprint 
you need looks to be the QFP65P1600X2200X160-100L.  This does not 
match the height of your part, 1.6 mm vs. 1.4 mm.  But otherwise has 
the same dimensions.
