Compliant layer for encapsulated columns

An electronic package comprising:

• a substrate having a first and second surface, said first surface having a first plurality of conductive contacts thereon and said second surface having a second plurality of conductive contacts thereon adapted for connection to an electrical component;
• a layer of dielectric material having a first and second surface, said first surface of said dielectric material positioned substantially on said first surface of said substrate;
• at least one through hole positioned in said layer of dielectric material substantially aligned with at least one of said first plurality of said conductive contacts, said at least one through hole having a side wall;
• a conductive material positioned in said at least one through hole, said conductive material substantially filling said through hole and being in electrical contact with said at least one of said first plurality of conductive contacts;
• and
• at least one solder ball positioned on said conductive material in said at least one through hole and in electrical contact with said conductive material.
