Abstract:
The instant disclosure includes a magnetic coupling package structure with duo leadframes for a magnetically coupled isolator and a method for manufacturing the same. The method includes a leadframe providing step, a chip connecting step and a coil alignment step. The leadframe providing step includes providing a first and a second leadframe each including a chip carrying portion, a coil portion, a plurality of pins and floating pins. The chip connecting step includes disposing at least a first chip and at least a second chip onto the corresponding chip carrying portions for electrically connecting the chips to the pins. The coil alignment step includes arranging the first leadframe above or beneath the second leadframe and applying a first and a second magnetic field to the first and the second leadframes respectively for aligning the coil portions, thereby controlling the coupling effect between two coil portions.

Claim (Index 6):
A magnetic coupling package structure with duo leadframes for a magnetically coupled isolator, comprising:\n a first leadframe including a first chip-mounting portion, at least a first coil portion, a plurality of first pins and a plurality of first floated pins; a second leadframe including a second chip-mounting portion, at least a second coil portion, a plurality of second pins and a plurality of second floated pins; a first chip disposed on the first chip-mounting portion; a second chip disposed on the second chip-mounting portion; and an insulating packaging body packaging the first chip and the second chip and connecting the first leadframe to the second leadframe, wherein a portion of each of the first pins is exposed from the insulating package body, and a portion of each of the second pins is exposed from the insulating package body, the portion of each of the first pins and the portion of the second pins are configured to respectively provide an isolating voltage to the first leadframe and the second leadframe; wherein the first leadframe is disposed at a location above or under the second leadframe, the first leadframe and the second leadframe having a height difference therebetween, the first leadframe and the second leadframe being galvanically isolated from each other, and the first coil portion and the second coil portion match with each other for generating magnetic coupling.
