Patent ID: 7201304

Claim:
A method of processing a microelectronic component which has a first surface bearing a plurality of component electrical terminals, comprising: depositing a plurality of solder deposits, with each solder deposit being deposited on a different one of the component electrical terminals and comprising: an electrically conductive metal; a first fluxing agent; and a second fluxing agent; heating the solder deposits to a ball attach reflow temperature, the first fluxing agent reacting with an oxide of the electrically conductive metal to promote flow of the solder deposits at the ball attach reflow temperature; and allowing the solder deposits to cool to a temperature below the ball attach reflow temperature, each cooled solder deposit defining a solid solder ball attached to a component electrical terminal and each solder ball including a sufficient amount of the second fluxing agent efficacious to promote flow of the solder at a temperature higher than the ball attach reflow temperature.
