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.
