Fill head interface with combination vacuum pressure chamber

摘要

A fill head apparatus includes at least one chamber for holding a fluid. The chamber has an outlet for expelling the fluid. A vacuum device has an inlet for a suction device adjacent to the fluid outlet. A plurality of flexible and resilient sealing devices contact a top surface of a workpiece. The sealing devices are positioned on opposing sides of the chamber outlet and on opposing sides of the vacuum device inlet, such that the sealing devices create at least a partial seal around a cavity defined by the workpiece and the cavity is beneath both the chamber outlet and the vacuum outlet.

1. A fill head apparatus, comprising:
at least one chamber for holding a fluid, the chamber having an outlet for expelling the fluid; at least one vacuum device having a vacuum inlet adjacent to the fluid outlet; and a flexible and resilient unified seal assembly contacting a top surface of a workpiece having defined therein at least a first cavity and a second cavity, wherein the unified seal assembly consists of a solder fill region that is above the first cavity and under the fluid outlet, a vacuum region that is above the second cavity and under the vacuum inlet, and seals with curved heads configured to contact the top surface of the workpiece, wherein the seals of the unified seal assembly create at least a first seal around the fluid outlet and the vacuum inlet such that each of the fluid outlet and the vacuum inlet are sealed off from ambient pressure, wherein the seals of the unified seal assembly create at least a second seal between the fluid outlet and the vacuum inlet such that each of the fluid outlet and the vacuum inlet are sealed off from one another.
