Integrated circuit package system with shield and tie bar
An integrated circuit package system includes: providing a tie bar and a lead adjacent thereto; connecting an integrated circuit and the lead; mounting a shield over the integrated circuit with the shield connected to the tie bar; and encapsulating the integrated circuit and the shield. An integrated circuit package system also includes: forming a lead and a support structure with substantially the same material as the lead and elevated above the lead; connecting an integrated circuit and the lead; mounting a shield over the integrated circuit with the shield on the support structure; and encapsulating the integrated circuit and the shield.
1. A method for manufacturing an integrated circuit package system comprising:
providing a tie bar; and
providing a lead adjacent to the tie bar;
connecting an integrated circuit and the lead;
mounting a shield, having a shield base which is horizontal, over the integrated circuit with the shield connected to the tie bar, and with a bottom surface of the shield base coplanar with a bottom surface of the lead; and
encapsulating the integrated circuit and the shield.
2. The method as claimed in claim 1 wherein mounting the shield includes mounting the shield base with the tie bar in between.
3. The method as claimed in claim 1 wherein:
providing the tie bar includes the tie bar having a slot; and
mounting the shield includes mounting the shield base within the slot of the tie bar.
4. The method as claimed in claim 1 wherein mounting the shield over the integrated circuit with the shield connected to the tie bar includes fitting the shield base with the tie bar.
5. The method as claimed in claim 1 wherein mounting the shield over the integrated circuit with the shield connected to the tie bar includes pressing an interlock to the shield towards the tie bar.
6. A method for manufacturing an integrated circuit package system comprising:
providing a tie bar extending from a paddle;
providing a lead adjacent to the tie bar;
connecting an integrated circuit over the paddle and to the lead;
mounting a shield, having a shield base which is horizontal, over the integrated circuit with the shield connected to the tie bar, and with a bottom surface of the shield base coplanar with a bottom surface of the lead;
encapsulating the integrated circuit and the shield; and
grounding the shield.
7. The method as claimed in claim 6 wherein:
encapsulating the shield includes exposing the shield base of the shield; and
grounding the shield includes grounding the shield base.
8. The method as claimed in claim 6 wherein mounting the shield over the integrated circuit with the shield connected to the tie bar includes connecting a shield interconnect between the shield and the tie bar.
9. The method as claimed in claim 6 wherein mounting the shield over the integrated circuit with the shield connected to the tie bar includes a support of the shield having a tapered configuration and the support is wedged into a slot in the tie bar.
10. The method as claimed in claim 6 wherein mounting the shield includes mounting the shield base of the shield with the shield base having a coating.
11. An integrated circuit package system comprising:
a tie bar and a lead adjacent thereto;
an integrated circuit connected with the lead;
a shield over the integrated circuit with the shield connected to the tie bar;
a shield base, which is horizontal, connected to the tie bar and the shield, with a bottom surface of the shield base coplanar with a bottom surface of the lead; and
an encapsulation over the integrated circuit and at least a portion of the shield.
12. The system as claimed in claim 11 wherein:
the tie bar is between the shield base.
13. The system as claimed in claim 11 wherein:
the tie bar includes a slot; and
the shield includes the shield base within the slot of the tie bar.
14. The system as claimed in claim 11 wherein:
the shield base is fitted to the tie bar.
15. The system as claimed in claim 11 further comprising an interlock pressed to the shield towards the tie bar.
16. The system as claimed in claim 11 wherein:
the tie bar extends from the paddle;
the integrated circuit is over the paddle; and
the shield is grounded.
17. The system as claimed in claim 16 wherein:
the encapsulation exposes the shield base of the shield; and
the shield is grounded through the shield base.
18. The system as claimed in claim 16 further comprising a shield interconnect between the shield and the tie bar.
19. The system as claimed in claim 16 wherein:
the shield includes a support having a tapered configuration; and
the support is wedged into a slot in the tie bar.
20. The system as claimed in claim 16 wherein the shield includes the shield base having a coating.
