Abstract

Abstract In contrast to the conventional automated bonding system, an electronic device (10) is mounted within a surrounding ring frame (12, 14) of insulating material by means of a plurality of individually applied tapes or ribbons (16) of electrically conductive material. A protective coating (18) may be applied to the assembly after bonding.
