Patent ID: 7757378

Claim:
A method of manufacturing a data storage device, comprising: pressurizing a first tank at a selected pressure, the first tank enclosing a housing component of a data storage device; pressurizing a second tank at substantially the same pressure as the first tank, the second tank fluidically coupled to the first tank and enclosing a sealant; gradually increasing said pressure of the second tank to induce and maintain a continuous laminar flow of the sealant from the second tank to the first tank, at least a portion of said sealant in the first tank contactingly permeating voids in the housing component; and transferring the sealant from the first tank back to the second tank by gradually increasing said pressure of the first tank to induce and maintain a continuous laminar flow of the sealant from the first tank to the second tank and to reduce introduction of gas bubbles in the sealant during the entirety of said transfer to the second tank.
