Abstract

A die package having mixed impedance leads where a first lead has a first metal core, and a dielectric layer surrounding the first metal core, and a second lead has a second metal core, and a second dielectric layer surrounding the second metal core, with the dielectric thicknesses differing from each other. A method of making a die package having leads with different impedances formed by connecting the die package to the die substrate connection pads via a first wirebond having a first metal core, depositing a dielectric layer on the wirebond metal core, metalizing the dielectric layer, connecting the die package to the die substrate connection pads via a second wirebond having a second metal core, depositing a dielectric layer on the second wirebond second metal core, and metalizing the dielectric layer on the second metal core, such that the first wirebond has a different impedance than the second wire bond.
