Abstract:
A system for dispensing an underfill material between an integrated circuit (IC) chip and a substrate includes a platform at which the underfill material is supplied. The IC chip and the substrate are mounted at the periphery of the platform. The platform rotates and facilitates the movement of the underfill material toward the IC chip and the substrate. The system further includes a Bernoulli tube that is located proximate to the IC chip and the substrate. The Bernoulli tube generates a low pressure in the proximity of the IC packages. The low pressure facilitates the dispensing of the underfill material between the IC chip and the substrate.
