Abstract

A casing for semiconductor packages that includes a plurality of press-fit pins is disclosed. Specific implementations include a shaft including a first end and a second end. The first end may include a head. The press-fit pin may include a bonding portion included at the second end. The bonding portion may include a first section extending substantially perpendicular from a longest length of the shaft. The bonding portion may also include an angled section coupled to a bonding foot. The bonding foot may be configured to be ultrasonically welded to a substrate.

Claims (31)

1 . A press-fit pin for a semiconductor package, comprising:

a shaft comprising a first end and a second end, the first end comprising a head;

a bonding portion comprised at the second end, the bonding portion comprising a first section extending substantially perpendicular from a longest length of the shaft, the bonding portion further comprising an angled section coupled to a bonding foot;

wherein the bonding foot is configured to be ultrasonically welded to a substrate.

2 . The press-fit pin of claim 1 , wherein the shaft comprises a cylinder.

3 . The press-fit pin of claim 1 , wherein the shaft comprises a rectangular prism.

4 . The press-fit pin of claim 1 , wherein a surface of the bonding foot is substantially planar with the substrate.

5 . The press-fit pin of claim 1 , wherein the press-fit pin is configured to extend from a casing.

6 . The press-fit pin of claim 1 , wherein the press-fit pin is further configured to be molded into a casing.

7 . The press-fit pin of claim 1 , wherein the press-fit pin is configured to electrically couple the substrate to a printed circuit board.

8 . A housing for a semiconductor package, comprising:

a casing; and

a plurality of connectors extending from the casing; and

a plurality of press-fit pins extending from the casing;

wherein the plurality of press-fit pins and the plurality of connectors are molded into the casing; and

wherein the plurality of press-fit pins and at least a portion of each of the plurality of connectors are configured to be ultrasonically welded to a substrate.

9 . The housing of claim 8 , wherein each press-fit pin of the plurality of press-fit pins comprises a shaft comprising a first end and a second end, the first end comprising a head.

10 . The housing of claim 9 , wherein each press-fit pin of the plurality of press-fit pins further comprises a bonding portion comprised at the second end, the bonding portion comprising a first section extending substantially perpendicular from a longest length of the shaft, the bonding portion further comprising an angled section coupled to a bonding foot.

11 . The housing of claim 10 , wherein a surface of the bonding foot is substantially planar with the substrate.

12 . The housing of claim 9 , wherein the shaft comprises a rectangular prism.

13 . The housing of claim 8 , wherein the press-fit pins are only ultrasonically bonded.

14 . The housing of claim 8 , wherein each press-fit pin of the plurality of press-fit pins is configured to electrically couple the substrate to a printed circuit board.

15 . A method of forming a housing for a semiconductor package, comprising:

molding a plurality of press-fit pins into a casing;

placing the casing over a substrate; and

ultrasonically bonding the plurality of press-fit pins to the substrate.

16 . The method of claim 15 , wherein each press-fit pin of the plurality of press-fit pins is configured to electrically couple with a printed circuit board.

17 . The method of claim 15 , wherein the press-fit pins are only ultrasonically bonded.

18 . The method of claim 15 , wherein each press-fit pin of the plurality of press-fit pins comprises a shaft comprising a first end and a second end, the first end comprising a head.

19 . The method of claim 18 , wherein each press-fit pin of the plurality of press-fit pins further comprises a bonding portion comprised at the second end, the bonding portion comprising a first section extending substantially perpendicular from a longest length of the shaft, the bonding portion further comprising an angled section coupled to a bonding foot.

20 . The method of claim 19 , wherein a surface of the bonding foot is substantially planar with the substrate.
