Abstract

Claims (22)

1. A ribbon bonding tool comprising:

a body portion including a tip portion,

the tip portion including a working surface, the tip portion including two side wall portions extending along an exterior surface of at least a portion of a back side of the ribbon bonding tool wherein a ribbon path is defined along the exterior surface between the t.wo side wall portions such that a ribbon material is guided from the ribbon path to the working surface.

2. The ribbon bonding tool of claim 1 wherein the side wall portions are tapered.

3. The ribbon bonding tool of claim 1 wherein the side wall portions are curved.

4. The ribbon bonding tool of claim 1 wherein the two side wall portions extend at least partially along a bottom edge of the ribbon bonding tool such that the ribbon path is defined along at least a portion of the back side of the ribbon bonding tool and along at least a portion of the bottom edge.

5. An ultrasonic ribbon bonding machine comprising:

a ribbon bonding tool having a body portion including a tip portion, the tip portion including a working surface, the tip portion including two side wall portions extending along an exterior surface of at least a portion of a back side of the ribbon bonding tool wherein a ribbon path is defined between the two side wall portions; and

a ribbon supply including ribbon to be bonded to a workpiece using the ribbon bonding tool, the ribbon being guided toward the working surface of the ribbon bonding tool using the two side wall portions along the exterior surface to align the ribbon therebetween.

6. The ultrasonic ribbon bonding machine of claim 5 wherein the side wall portions are tapered.

7. The ultrasonic ribbon bonding machine of claim 5 wherein the side wall portions are curved.

8. The ultrasonic ribbon bonding machine of claim 5 wherein the two side wall portions extend at least partially along a bottom edge of the ribbon bonding tool such that the ribbon path is defined along at least a portion of the back side of the ribbon bonding tool and along at least a portion of the bottom edge.

9. The ribbon bonding tool of claim 1 wherein a width between the two side wall portions is substantially the same as a width of the ribbon material.

10. The ribbon bonding tool of claim 1 wherein the working surface defines a plurality of protrusions and a plurality of recesses.

11. The ribbon bonding tool of claim 10 wherein the plurality of protrusions define rounded edges.

12. The ribbon bonding tool of claim 1 wherein the working surface defines a plurality of protrusions and a plurality of recesses in a waffle type configuration.

13. The ribbon bonding tool of claim 12 wherein the plurality of protrusions define rounded edges.

14. The ultrasonic ribbon bonding machine of claim 5 wherein a width between the two side wall portions is substantially the same as a width of the ribbon material.

15. The ultrasonic ribbon bonding machine of claim 5 wherein the working surface defines a plurality of protrusions and a plurality of recesses.

16. The ultrasonic ribbon bonding machine of claim 15 wherein the plurality of protrusions define rounded edges.

17. The ultrasonic ribbon bonding machine of claim 5 wherein the working surface defines a plurality of protrusions and a plurality of recesses in a waffle type configuration.

18. The ultrasonic ribbon bonding machine of claim 17 wherein the plurality of protrusions define rounded edges.
