ABSTRACT:
A lead frame assembly characterized by alternating high and low wire loops which connect the attach pads of an integrated circuit die to the conductive fingers of the lead frame. The alternating loops reduce the likelihood that adjacent loops will short out due to twists in the wires or due to connecting wire "sweep" caused by subsequent plastic encapsulation. A number of high loops can be attached before the formation of the first low loop or vice versa. Alternately, the high and low wire loops can be attached in an alternating fashion.
