ABSTRACT:
A method of making a microelectronic assembly buying restraining a substrate in a fixture at room temperature, placing a flip chip on the substrate so that conductive bumps on the flip chip are aligned with contact pads on the substrate, heating the flip chip, the substrate and the fixture to reflow the conductive bumps on the flip chip, cooling the flip chip, substrate and fixture to solidify the conductive bumps and to mount the flip chip to the substrate, depositing an underfill between the flip chip and the substrate, curing the underfill by heating the flip chip, substrate, underfill and fixture to an elevated temperature, and removing the flip chip mounted substrate from the fixture.
