Re: gEDA-user: ALPS 6mm tactile footprint

[Steve Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

Your pins have no clearances from copper polygons

pin[x y padwidth clearence soldermask drill_width .......]

Having no clearance all four pins will short if they are placed in a
board with power and ground planes.

Has anyone got a list of "standard drill sizes"
