Abstract

The instant disclosure provides a method for manufacturing a package structure of a folding magnetic coupling isolator. The method includes providing a leadframe structure including a frame body and a first and a second leadframes connected to the frame body, the first and second leadframes including first and second chip-mounting portions, first and second coil portions, and a plurality of first and second pins and floated pins; disposing the first and second chips on the first and second chip-mounting portions and establishing electrical connections between the first and second chips and the first and second pins; and rotating the first leadframe relative to the frame body and moving the first leadframe to a position above or under the second leadframe, thereby electrically isolating the first leadframe from the second leadframe. The first coil portion and the second coil portion are aligned with and magnetically coupled to each other.
