You will find that they are industry standard foot prints - most will be in 
kicad Libs already (lots 
out there on the web ) there is also a tool to convert all the Eagle footprints.

There is also a free software tool from IPC that lets you tweak footprint 
patterns for different 
compromises (density vs reliability). footprints from the manufactures might be 
optimized in a way 
that doesn't fit your goals. Surface mount processes can be picky on fine pitch 
- avoid using 
no-lead processes if at all possible ( Europes ban of lead in solder is not 
based on sound science 
anyway - the lead leaching from landfills is from crushed CRTs - not circuit 

BTW - there are several auto-routers that kicad works with - I use different 
ones depending on the 

Anyway - if you have more questions - it probably belongs on the kicad mailing
