Abstract

A system for removal of an integrated circuit from a mount material including holding and stretching the mount material using linear and rotary motion, and removing the integrated circuit from the mount material when the mount material is stretched by linear and rotary motion.

Claims (30)

1. A method for removal of an integrated circuit from a mount material comprising:

holding and stretching the mount material using linear and rotary motion; and

removing the integrated circuit from the mount material when the mount material is stretched by linear and rotary motion.

2. The method as claimed in claim 1 wherein holding and stretching the mount material comprises applying a centrifugal force to the mount material.

3. The method as claimed in claim 1 wherein holding and stretching the mount material comprises applying a removal force partially opposite a mount material expansion direction.

4. The method as claimed in claim 1 wherein removing the integrated circuit comprises stretching the mount material away from the integrated circuit.

5. The method as claimed in claim 1 wherein removing the integrated circuit comprises lifting the integrated circuit off the mount material.

6. A method for removal of an integrated circuit from a mount material comprising:

holding and stretching the mount material using linear and rotary motion;

dispersing stretching forces across the range of linear and rotary motion; and

removing the integrated circuit from the mount material when the mount material is stretched by linear and rotary motion.

7. The method as claimed in claim 6 wherein dispersing stretching forces comprises applying a centrifugal force across a range of the rotary motion.

8. The method as claimed in claim 6 wherein dispersing stretching forces comprises applying the stretching force across a width of a removal region.

9. The method as claimed in claim 6 wherein dispersing stretching forces comprises varying a velocity of the rotary motion.

10. The method as claimed in claim 6 wherein holding and stretching the mount material comprises applying a vacuum for holding the mount material.

11. A system for removal of an integrated circuit from a mount material comprising:

a removal device having a scissor blade assembly for removing the integrated circuit from the mount material;

a base having the blade attached for stretching the mount material; and

a housing near the removal device and the base for holding the mount material.

12. The system as claimed in claim 11 wherein the base is a motion generator.

13. The system as claimed in claim 11 wherein the removal device comprises a single blade.

14. The system as claimed in claim 11 wherein:

the removal device is a removal device having a blade for removing the integrated circuit from the mount material;

the base is a motion generator having the blade attached for stretching the mount material;

the housing is a housing for holding the mount material and the integrated circuit; and further comprising:

a pick-up device for lifting the integrated circuit from the mount material.

15. The system as claimed in claim 14 wherein the removal device comprises a first scissor blade and a second scissor blade connected by a pivot.

16. The system as claimed in claim 14 wherein the motion generator comprises a rotary motion.

17. The system as claimed in claim 14 wherein the motion generator comprises a substantially up-down motion.

18. The system as claimed in claim 14 wherein the housing comprises a suction housing having vacuum holes.
