Method and system for flip chip packaging

1. A method of packaging flip chips, comprising:

providing a plurality of flip chips and a panel;

forming a plurality of partitions outwardly from the panel, with a height between approximately 25 and 75 microns and a width between approximately 25 and 125 microns;

coupling the flip chips to the panel such that each partition surrounds a respective flip chip; and

forming an underfill region between each of the flip chips and the panel, whereby each partition prevents a respective underfill region from engaging an adjacent underfill region.

2. The method of claim 1 , further comprising forming the partitions from a metal.

3. The method of claim 1 , further comprising forming the partitions from a polymer.

4. The method of claim 1 , further comprising:

encapsulating each flip chip with a molding; and

coupling a plurality of solder balls to a surface of the panel opposite the flip chips.

5. The method of claim 1 , further comprising forming the partitions such that a gap between any adjacent partitions is at least 0.1 millimeters.

6. A method of packaging flip chips, comprising:

providing a plurality of flip chips and a panel;

forming a plurality of partitions outwardly from the panel;

coupling the flip chips to the panel such that any two adjacent flip chips have two respective partitions between them, the two respective partitions being separated by a gap with a width of at least 0.1 millimeters;

forming an underfill region between each of the flip chips and the panel such that any two adjacent underfill regions are separated by at least the gap; and

directing a cutting device between the respective partitions to singulate the flip chips.

7. The method of claim 6 , wherein directing the cutting device comprises directing a saw blade.

8. The method of claim 6 , further comprising forming the partitions from a metal.

9. The method of claim 6 , further comprising forming the partitions from a polymer.

10. The method of claim 6 , further comprising:

encapsulating each flip chip with a molding; and

coupling a plurality of solder balls to a surface of the panel opposite the flip chips.

11. The method of claim 6 , further comprising forming the partitions with a height between approximately 25 and 75 microns and a width between approximately 25 and 125 microns.

12. A system for packaging flip chips, comprising:

a plurality of flip chips coupled to a panel;

a plurality of partitions formed outwardly from the panel with a height between approximately 25 and 75 microns and a width between approximately 25 and 125 microns, each partition surrounding a respective flip chip;

a plurality of underfill regions formed outwardly from the panel, each underfill region disposed between a respective flip chip and the panel; and

whereby each partition prevents a respective underfill region from engaging an adjacent underfill region.

13. The system of claim 12 , further comprising a cutting device operable to singulate the flip chips, the cutting device configured to singulate the flip chips between adjacent partitions.

14. The system of claim 12 , wherein partitions are formed from a metal.

15. The system of claim 12 , wherein the partitions are formed from a polymer.

16. The system of claim 12 , further comprising:

a molding configured to encapsulate each flip chip; and

a plurality of solder balls coupled to a surface of the panel opposite the flip chips.

17. The system of claim 12 , wherein the partitions are formed on the panel such that a gap between any adjacent partitions is at least 0.1 millimeters.
