Abstract:
1. A dual layered lead frame comprising: a die bonding layer; a solder layer; a plurality of individually arranged dual layered lead frame cells to form into a matrix layout; and a plurality of cell gaps being formed between the dual layered lead frame cells, and each of the dual layered lead frame cells including a die bonding unit and a solder unit, wherein: the die bonding unit includes a plurality of first conductive leads and a first insulating clearance being formed between the first conductive leads, and each of the first conductive leads further comprises a plurality of first slot holes; the solder unit includes a plurality of second conductive leads and a second insulating clearance being formed between second conductive leads, and each of the second conductive leads further comprises a plurality of second slot holes; and an insulating material is filled in the respective first and second slot holes of the die bonding unit and the solder unit, the respective first and second insulating clearances of the die bonding unit and the solder unit, and the cell gaps, so that the first and second conductive leads are correspondingly joined closely.
