Abstract

Connectors and methods to couple packages and dies are shown. Selected examples include plugs and receptacles having two or more terraces with contacts provided along the terraces. Examples of connectors and methods include configurations where the connector is usable with a package including a die coupled along a substrate. In selected examples a heat sink is coupled over the die, and a package includes a side access port between the heat sink and the substrate configured to receive the connector, such as one or more of a plug or receptacle through the side access port.

Claims

1. A connector and package assembly comprising:

a package including a die coupled along a substrate, the package includes;

a side access port on a side of the package, and

a contact array on a bottom of the package, the contact array arranged for coupling with a socket;

a heat sink coupled over the die, and the side access port is between the heat sink and the substrate; and

a connector including;

a plug coupled with one or more of the package or substrate at the side access port, the plug having a plurality of contacts provided on two or more plug terraces, the two or more plug terraces are in a stepped arrangement, and

a receptacle arranged for coupling with the plug and a cable, the receptacle having a plurality of contacts provided on two or more receptacle terraces, the two or more receptacle terraces are in a corresponding stepped arrangement to the two or more plug terraces.

2. The connector and package assembly of claim 1 comprising a package clip coupling the heat sink with the substrate, the package clip includes a receptacle guide having one or more guide surfaces and the side access port is within the receptacle guide, the plug is positioned within the receptacle guide, and the receptacle guide is arranged to align and guide coupling of the receptacle with the plug.

3. The connector and package assembly of claim 1, the one or more guide surfaces include lateral guide surfaces, and a side access port width and a receptacle width correspond to a distance between the lateral guide surfaces.

4. The connector and package assembly of claim 1, a side access port height and a receptacle height correspond to a distance between a heat sink overhang of the heat sink and a topside substrate face.

5. The connector and package assembly of claim 1, a side access port length and a receptacle length correspond to a distance from the plug to an edge of the heat sink overhang.

6. The connector and package assembly of claim 5, the receptacle includes a receptacle insertion arm extending from a receptacle body having the two or more receptacle terraces, the receptacle insertion arm extending the respective side access port length and the receptacle length.

7. The connector and package assembly of claim 1, the side access port, the plug and the receptacle are arranged for horizontal coupling on the side of the package.

8. The connector and package assembly of claim 1, one of the plug or the receptacle is a plug and the other of the receptacle or the plug is a plug.

9. A method of connecting a package comprising:

installing a package in a socket; and

connecting the package with a work piece through a side access port and a contact array of the package, connecting including;

inserting a receptacle coupled with a cable into the side access port, the side access port between a heat sink and a substrate of the package,

engaging plug contacts along two or more receptacle terraces of the receptacle with receptacle contacts along two or more plug terraces of a plug, the plug at the side access port, and

engaging the contact array with a circuit board of the work piece, the contact array on a bottom side of the package.

10. The method of claim 9 comprising guiding the receptacle with a receptacle guide between the substrate and a heat sink overhang of the heat sink.

11. The method of claim 9, connecting the package with the work piece through the side access port includes interfitting the two or more receptacle terraces of the receptacle with the two or more plug terraces of the plug.

12. The method of claim 9, connecting the package includes pushing the receptacle into the side access port with a receptacle insertion arm extending from a receptacle body of the receptacle.

13. The method of claim 12 comprising retaining two or more cables along the receptacle insertion arm, retaining the two or more cables decreasing interface stress between the two or more cables and a plurality of cable contacts of the receptacle.

14. The method of claim 9, connecting the package includes connecting the connector while the heat sink is coupled with the package, and the heat sink overhangs the package.

15. The method of claim 9 connecting the package includes inserting a second receptacle coupled with a second cable into a second side access port, the second side access port between the heat sink and the substrate of the package.
