Abstract

A method of manufacture of an integrated circuit packaging system includes: providing a carrier; mounting an integrated circuit device having component connectors directly on the carrier; placing a restraint structure over the integrated circuit device for controlling warpage of the integrated circuit device during bonding of the component connectors to the carrier causing some of the component connectors to separate from the carrier; and bonding all of the component connectors to the carrier.

Claims (29)

1. A method of manufacture of an integrated circuit packaging system comprising:

providing a carrier;

mounting an integrated circuit device having component connectors directly on the carrier;

placing a restraint structure over the integrated circuit device, wherein placing the restraint structure includes placing ends of the restraint structure in a channel of the carrier, wherein the restraint structure controls warpage of the integrated circuit device during bonding of the component connectors to the carrier and prevents separation of the component connectors from the carrier; and

bonding all of the component connectors to the carrier; and

wherein the integrated circuit device has contact marks from contacting the restraint structure on an upper most edge of the integrated circuit device.

2. The method as claimed in claim 1 wherein the restraint structure comprises a cover lid having an inner cover height based on a threshold warpage.

3. The method as claimed in claim 1 wherein bonding all of the component connectors includes holding the restraint structure by weight of the restraint structure.

4. The method as claimed in claim 1 wherein bonding all of the component connectors includes holding the restraint structure by electromagnetic force.

5. The method as claimed in claim 1 wherein bonding all of the component connectors includes holding the restraint structure by fastened force.

6. A method of manufacture of an integrated circuit packaging system comprising:

providing a carrier;

mounting an integrated circuit device having component connectors directly on the carrier;

placing a restraint structure over the integrated circuit device, wherein placing the restraint structure includes placing ends of the restraint structure in a channel of the carrier, wherein the restraint structure controls warpage of the integrated circuit device during bonding of the component connectors to the carrier and prevents separation of the component connectors from the carrier;

bonding all of the component connectors to the carrier, wherein during said bonding of all component connectors to the carrier, the restraint structure is in direct contact with the integrated circuit device and the integrated circuit device has contact marks from contacting the restraint structure on an upper most edge of the integrated circuit device.

7. The method as claimed in claim 6 further comprising removing the restraint structure from the carrier.

8. The method as claimed in claim 6 wherein the restraint structure comprises a cover lid.

9. The method as claimed in claim 6 wherein placing the restraint structure includes placing the restraint structure such that the restraint structure is separated from the integrated circuit device.

10. An integrated circuit packaging system comprising:

a carrier; and

an integrated circuit device having all component connectors bonded to the carrier, the integrated circuit device has contact marks from contacting a restraint structure on an upper most edge of the integrated circuit device, wherein the restraint structure includes ends of the restraint structure in a channel of the carrier, and the restraint structure controls warpage of the integrated circuit device and prevents separation of the component connectors from the carrier.

11. The system as claimed in claim 10 wherein the restraint structure comprises a cover lid having an inner cover height based on a threshold warpage.

12. The system as claimed in claim 10 wherein the restraint structure is held by weight of the restraint structure.

13. The system as claimed in claim 10 wherein the restraint structure is held by electromagnetic force.

14. The system as claimed in claim 10 wherein the restraint structure is held by fastened force.

15. The system as claimed in claim 10 wherein all of the component connectors are adjacent to the carrier with the restraint structure in direct contact with the integrated circuit device.

16. The system as claimed in claim 15 wherein the integrated circuit device includes the integrated circuit device having the contact marks on an inactive side of the integrated circuit device.

17. The system as claimed in claim 15 wherein the restraint structure includes the restraint structure separated from the integrated circuit device.

18. The system as claimed in claim 15 wherein the restraint structure comprises a cover lid directly on the integrated circuit device.
