Integrated circuit protruding pad package system
An integrated circuit package system is provided. A protruding pad is formed on a leadframe. A die is attached to the leadframe. The die is electrically connected to the leadframe. At least portions of the leadframe, the protruding pad, and the die are encapsulated in an encapsulant.
1. A method for manufacturing a package comprising:
providing a leadframe with a tie bar and leadframe connection bars;
punching the tie bar and optionally the leadframe connection bars to form protruding pads;
clamping the leadframe and the protruding pads in a mold;
attaching dies to the leadframe;
electrically connecting the dies to the leadframe with wires wherein the protruding pads protrude above the dies and are substantially the same height as the wires that couple the dies to the leadframe;
encapsulating at least portions of the leadframe, the protruding pads, the dies, and the wires in an encapsulant to form a protruding pad package including the protruding pads exposed from the encapsulant at the top surface and the bottom surface of the protruding pad package;
singulating the protruding pad package; and
attaching a package cover to the encapsulant, optionally with an adhesive.
2. The method as claimed in claim 1 wherein singulating the protruding pad package forms singulated protruding pad packages or singulated protruding pad-less packages.
3. A method for manufacturing a package comprising:
providing a leadframe with a tie bar and leadframe connection bars;
punching the a tie bar and optionally the leadframe connection bars to form protruding pads;
clamping the leadframe and the protruding pads in a mold;
attaching dies to the leadframe;
electrically connecting the dies to the leadframe with wires wherein the protruding pads protrude above the dies and are substantially the same height as the wires that couple the dies to the leadframe;
encapsulating at least portions of the leadframe, the protruding pads, the dies, and the wires in an encapsulant to form a protruding pad package including the protruding pads exposed from the encapsulant at the top surface and the bottom surface of the protruding pad package;
singulating the protruding pad package;
attaching a package cover to the encapsulant, optionally with an adhesive; and
securing the package cover with protruding legs optionally anchored in the protruding pads.
4. The method as claimed in claim 3 wherein singulating the protruding pad package forms singulated protruding pad packages or singulated protruding pad-less packages.
