Patent ID: 7989965

Claim:
A system for dispensing an underfill material between an integrated circuit (IC) chip and a substrate, comprising: a platform having one or more spaced outlet ports located at a first distance from a center of a first surface of the platform, wherein the underfill material is dispensed from the outlet ports onto the first surface of the platform, and wherein the IC chip and the substrate are mounted at a second distance from the center of the first surface; means for rotating the platform such that rotation of the platform facilitates movement of the underfill material toward the IC chip and the substrate; and a Bernoulli tube having one or more constriction sections, the constriction sections located proximate to the IC chip and the substrate, wherein each of the constriction sections has an opening, wherein a fluid is circulated in the Bernoulli tube to generate a low pressure at the openings, and wherein the low pressure at the openings facilitates dispensing of the underfill material between the IC chip and the substrate.
