Is there such a catalogue? A few years ago major manufacturers added the
preferred pad dimensions to the datasheets of parts, including for passives=
 like
resistors and capacitors. Plucking this data out of datasheets is very tedi=
ous
when verifying board layouts or when figuring out extreme space constraint
what-ifs. Surely there must be some catalogue of footprints? I was unable t=
o
find such a thing. By catalogue, I mean some form of electronic document sh=
owing
the pads and dimensions, not necessarily EDIF files and especially not pad
artwork stored in proprietary layout tools. I know how to find those and it=
's
tedious but trivial to print out a proof sheet of those. Basically I'd like=
 to
have proof sheets of pad layouts so I can pick and mix in what-if scenarios=
 and
to prepare boards for readiness to take several types of parts to be change=
d
later (at place time).
