Abstract:
An electronic circuit element comprising:a first insulating layer having at least one surface, at least a portion of said surface defining a first surface plane; at least one conductor along at least a portion of said at least one surface; a solder bump in communication with said at least one conductor, said solder bump protruding to an apex at a first level, said first level beyond said first surface plane, said solder bump including a surface; said surface of said first insulating layer, said at least one conductor, and said surface of said solder bump, defining a major surface of a predetermined shape; a second insulating layer along at least a portion of said major surface whereby at least a portion of said solder bump is exposed, said second insulating layer including portions extending laterally from said solder bump along said first insulating layer, said laterally extending portions extending from said first surface plane to a second level, said second level not extending beyond said first level wherein said second insulating layer includes an adhesive.
