Abstract:
1. A method of forming a device, comprising: providing an integrated circuit (IC) package comprising a connector and an IC, and a molding compound, the molding compound encapsulating a portion of the connector, wherein a portion of the connector protrudes above a topmost surface of the molding compound; providing a printed circuit board (PCB) comprising a PCB contact pad; selectively applying a polymer flux to the portion of the connector that protrudes above the topmost surface of the molding compound; and after selectively applying the polymer flux, bringing the IC package into contact with the PCB and forming a connection between the PCB contact pad and the connector, wherein the polymer flux covers at least a part of the connector and extends over the topmost surface of the molding compound after the IC package and the PCB are brought into contact.
