To make a PGA instead of a BGA:
add these immediately after the def bga(attrlist): line
drill = findattr(attrlist, "drill")
paddia = findattr(attrlist, "paddia")
polyclear = findattr(attrlist, "polyclear")
maskclear = findattr(attrlist, "maskclear")

change
bgaelt = bgaelt + ball(x, y, balldia, polyclear, maskclear, ballname(col,row))
to
bgaelt = bgaelt + pin(x,y,paddia,drill,ballname(col,row),polyclear,maskclear)

You will need to define drill, paddia, polyclear and maskclear in
addition to the usual BGA parameters.

It would be possible to add a PGA mode to footgen, but I don't want a
patch as they are relatively rare.
