    Abstract: A leadframe strip includes a plurality of unit leadframes connected to a periphery of the leadframe strip, each unit leadframe having a die paddle, a plurality of leads and a semiconductor die attached to the die paddle. The leadframe strip is tested by electrically isolating at least the leads from the periphery of the leadframe strip such that at least some of the leads extend uninterrupted beyond a final lead outline of the unit leadframes after electrical isolation from the periphery of the leadframe strip. The semiconductor dies are tested, which includes probing the die paddles and the leads that extend uninterrupted beyond the final lead outline of the unit leadframes after electrical isolation from the periphery of the leadframe strip. The unit leadframes are severed from the leadframe strip along the final lead outline of the unit leadframes after testing the semiconductor dies.

    Abstract: A lead frame strip includes connected unit lead frames each having a die paddle, a tie bar directly connecting the die paddle to a periphery of the unit lead frame, leads directly connected to the periphery of the unit lead frame and projecting toward the die paddle, and an opening in the periphery adjacent the tie bar. The openings in the periphery of the unit lead frames are spanned with an electrically insulating material that connects the tie bar of each unit lead frame to the periphery of the unit lead frame. The direct connections between the tie bars and the periphery of the unit lead frames are severed prior to subsequent processing, so that the tie bars remain connected to the periphery of the unit lead frames by the electrically insulating material and the die paddles are electrically disconnected from the periphery of the unit lead frames.
