Abstract:
A leadframe adapted for coupling with a semiconductor integrated circuit, the leadframe comprising:a first set of conductors extending from a first end to a second end; a second set of conductors extending from the first end to a third end, the first end of the first and second sets of conductors being adapted for coupling with an electronic system, the second end of the first set of conductors and the third end of the second set of conductors being adapted for coupling with the semiconductor integrated circuit; each of the first set of conductors including an arcuate shape portion between the first and second ends, at least a portion of the arcuate shape portion exhibiting a constant radius, wherein the arcuate shape portion of one of the conductors of the first set of conductors has a different arc length than the arcuate shape portion of at least one other conductor of the first set of conductors, at least two conductors of the first set of conductors are sized and spaced such that line spacing between the at least two conductors of the first set of conductors is constant through at least the arcuate shape portions of the at least two conductors, and at least one conductor of the first set of conductors includes a constant width through the arcuate shape portion; and each of the second set of conductors extending substantially straight from the first end to the third end.
