Abstract: The present invention increases real estate by providing non-annular lands which do not completely encircle the through holes. The non-annular lands are non-annular, that is they do not extend 360.degree. around the through hole. Preferably the non-annular lands contact no more than one side of the through holes thereby providing real estate not otherwise available using conventional lands. The present invention also relates to a method for producing such Non-annular lands.
