Abstract
A conductive clip having a riser or post formed along a side thereof includes a notch or opening formed in the riser or post to create a first riser or post section and second riser or post section separated by the notch or opening through which a tiebar extends. The conductive clip organization is will suited for formation as elongated strips of such conductive clips for automated machine assembly of the conductive clips in an integrated circuit package context.
Claims16
A conductive clip for use in the fabrication of an integrated-circuit package, comprising:
- a conductive clip having a planar portion thereof defined by plural sides;
- a post formed along at least one side thereof and aligned at an angle relative to the planar portion, the post bifurcated by an opening intermediate ends thereof;
- a first tiebar extending from the planar portion of the conductive clip from the opening;
- and
- a second tiebar extending from the planar portion of the conductive clip from another one of the plural sides.
A conductive clip for use in the fabrication of an integrated-circuit package, comprising:
- a conductive clip having a planar portion thereof defined by lateral sides and longitudinal sides;
- a post formed along a one of said lateral and longitudinal sides thereof and aligned at an angle relative to the planar portion, the post bifurcated by an notch intermediate ends thereof;
- a first tiebar extending from the planar portion of the conductive clip from the notch;
- and
- a second tiebar extending from the planar portion of the conductive clip from another one of said lateral and longitudinal sides.
A conductive clip for use in the fabrication of an integrated-circuit package, comprising:
- a conductive clip having a planar portion thereof defined by plural sides;
- a post formed along at least one side thereof and aligned at an angle relative to the planar portion, the post bifurcated by a gap intermediate ends thereof into a first section and a second section;
- a first tiebar extending from the planar portion of the conductive clip from the gap between said first and second sections of said post;
- and
- a second tiebar extending from the planar portion of the conductive clip from another one of said plural sides.
A plurality of connected conductive clips for use in the fabrication of an integrated-circuit package, comprising:
- an elongated strip defined by at least first and second spaced-apart rails;
- at least a first and at least a second conductive clip spaced apart along said first and second rails, each conductive clip having a planar portion thereof defined by plural sides and a post formed along at least one side thereof and aligned at an angle relative to the planar portion, the post bifurcated by a gap intermediate ends thereof;
- a first tiebar extending from the planar portion of the conductive clip from the gap and connected to a one or said first and second rails;
- and
- a second tiebar extending from the planar portion of the conductive clip from another one of the plural sides and connected to the other of said first and second rails.
