Hi Scott !
Aperture size : See Phillips, " IC Package Databook", Phillips
Semiconductors, page 5 - 2 , it states that dimensions
of the openings should be about 10 % smaller than those of the lands ( see
the tolerances
in paste printing process ) We are happy with this recommendation.
Hope this will help.
Brs, Johannes
