More Information
Summary:An exemplary method includes at a bonding temperature, bonding a semiconductor chip to an organic laminate substrate using solder; without cooldown from the bonding temperature to room temperature, at an underfill dispense temperature, dispensing underfill between the semiconductor chip and the organic laminate substrate; and curing the underfill within a range of temperatures above the underfill dispense temperature. Another exemplary method includes depositing a first solder on pads of an organic laminate substrate; contacting a second solder on pillars of a semiconductor chip to the first solder on the pads of the organic laminate substrate; and solder bonding the semiconductor chip to the organic laminate substrate.
