Abstract:
A lead frame, comprising:sheet metal having top and bottom opposing surfaces; a first set of leads formed in said sheet metal by etching a pattern into said top surface, each of said leads having a width dimension and each of said leads spaced from one another by a distance approximately the same as said width dimension, said leads having a thickness less than half of the distance between said top and bottom opposing surfaces; a second set of leads formed in said sheet metal by etching a pattern into said bottom surface, each of said leads having said width dimension and each of said leads spaced from one another by a distance approximately the same as said width dimension, said leads having a thickness less than half of the distance between said top and bottom opposing surfaces; wherein said second set of leads is offset from said first set of leads in a plane parallel to said top and bottom surfaces by a distance approximately equal to said width dimension; and further wherein said first and second sets of leads are separated from one another in a plane perpendicular to said top and bottom surfaces.
