Overhang integrated circuit package system
View Patent ↗An integrated circuit package system is provided attaching a film to a die paddle, applying an adhesive to the film, and attaching an integrated circuit die over the adhesive and the film to the die paddle.
1. An integrated circuit package system comprising:
attaching a film, having a pattern with an adhesive flow controlling feature, to a die paddle;
applying an adhesive to the film along the flow controlling feature; said film minimizes overflow of the adhesive, and
attaching an integrated circuit die over the adhesive and the film to the die paddle; and
forming a lead frame package includes the die paddle and lead fingers with the edges of the integrated circuit die elevated and overhanging the lead fingers.
2. The system as claimed in claim 1 further comprising forming a lead frame package with a configuration comprised of single row of lead fingers or multiple rows of the lead fingers.
3. The system as claimed in claim 1 wherein attaching the film to the die paddle comprises forming patterns of the film comprised of segments of the film with channels or an interior space within the film or a combination thereof.
4. The system as claimed in claim 1 wherein attaching the film comprises providing a space at edges of a surface with the film attached thereon.
5. A integrated circuit package system comprising:
forming a film with a pattern having an adhesive flow controlling feature;
attaching the film to a die paddle of a lead frame;
applying an adhesive to the pattern of the film along the flow controlling feature; said film minimizes overflow of the adhesive, and
attaching an integrated circuit die with the adhesive and the film to the die paddle comprising:
forming lead fingers of the lead frame; and
elevating an overhang of the integrated circuit die over the lead fingers with the film.
6. The system as claimed in claim 5 wherein attaching the film to the die paddle of the lead frame comprises forming a thermal dissipation path from the integrated circuit die to the die paddle with the adhesive within the film.
7. The system as claimed in claim 5 wherein attaching the film to the die paddle of the lead frame comprises forming ground connections between the die paddle and the integrated circuit within the film.
8. The system as claimed in claim 5 wherein applying the adhesive is comprised of a conductive material or nonconductive material.
9. An integrated circuit package system comprising:
a film, having a pattern with an adhesive flow controlling feature, attached to a die paddle;
an adhesive applied to the film along the flow controlling feature;
an integrated circuit die over the adhesive and the film to the die paddle; said film minimizes overflow of the adhesive, and
a lead frame package including the die paddle and lead fingers with the edges of the integrated circuit die elevated and overhanging the lead fingers.
10. The system as claimed in claim 9 further comprising a lead frame package with a configuration comprised of single row of lead fingers or two rows of the lead fingers.
11. The system as claimed in claim 9 wherein the film attached to the die paddle comprises patterns of the film comprised of segments of the film with channels or an interior space within the film or a combination thereof.
12. The system as claimed in claim 9 wherein the film comprises a space at edges of a surface with the film attached thereon.
13. The system as claimed in claim 9 wherein:
the film attached to the die paddle is cut to form,
the adhesive applied to the film is an epoxy, and
the integrated circuit die over the adhesive and the film to the die paddle has lateral dimensions larger than the die paddle;
further comprising:
the film is cut to form a pattern; and
the die paddle formed from a lead frame.
14. The system as claimed in claim 13 wherein the integrated circuit die with the adhesive and the film to the die paddle comprises:
lead fingers of the lead frame; and
an overhang of the integrated circuit die over the lead fingers with the film.
15. The system as claimed in claim 13 wherein the film attached to the die paddle of the lead frame is a thermal dissipation path from the integrated circuit die to the die paddle with the adhesive within the film.
16. The system as claimed in claim 13 wherein the film attached to the die paddle of the lead frame is ground connections between the die paddle and the integrated circuit die within the film.
17. The system as claimed in claim 13 wherein the adhesive is a conductive material or nonconductive material.
