Abstract
A semiconductor package ( ) has a die ( ), a leadframe ( ), a bond pad ( ), an encapsulation ( ) and a wire bond ball ( ). The wire bond ball is formed on the bond pad by bonding one end of a bond wire ( ), and remainder of the bond wire is removed. Locations ( ) for attaching the wire bond ball are recorded with reference to fiducials ( ) on the lead frame. The encapsulation covers the die, deposits and die attach flag ( ) of the lead frame. The wire bond ball is exposed where the encapsulation is removed. The locations for making openings ( ) for exposing the wire bond ball is determined by recorded coordinates when the wire bond ball is formed. Exposed wire bond ball is plated, forming a lead to electrically connect to the die.
