Abstract
An in situ stabilizing tool provides a stress relieved, ceramic green sheet for green sheet screened stability. A green sheet stablilization system uses air bearings as a means of conveying a continuous ceramic green sheet web in a frictionless and stress free state. Solvent vapor stabilization of green sheets in a continuous mode adjusts solvent concentration in the air bearing using a solvent bubbler. Solvent vapor is generated from a group of solvents (e.g. hydrocarbons, water, etc.) that can be vaporized and used to solvent plasticize the ceramic green sheets to achieve stress relaxation. Take up loops and sensors adjust for longitudinal shrinkage during the green sheet relaxation process.
