Abstract:
A method for forming a semiconductor package on a leadframe, the method comprising the sequential steps of(a) providing a semiconductor die, a leadframe, a plurality of wire bondings and an encapsulant; (b) mounting the semiconductor die on a flag portion of the leadframe, wherein at least one support portion extends from the flag portion to a peripheral portion of the leadframe; (c) connecting the plurality of wire bondings between terminals of the semiconductor die and at least some of a plurality of inner lead portions that extend inwardly from the peripheral portion of the leadframe proximal to the flag portion of the lead frame; (d) forming links that extend between the semiconductor package and a strip portion of the leadframe with the encapsulant to electrically isolate the semiconductor package from the leadframe; (e) severing outer lead portions and the support portion from the peripheral portion, wherein the outer lead portions are ends of the inner lead portions that are proximal to the peripheral portion; and (f) encapsulating the semiconductor die, the flag portion of the leadframe, the at least some of the plurality of inner lead portions of the leadframe, and the plurality of the wire bondings with the encapsulant, to form the semiconductor package.
