THICK FILM GREEN SHEET SLURRY, PRODUCTION METHOD OF THICK FILM GREEN SHEET SLURRY, PRODUCTION METHOD OF THICK FILM GREEN SHEET AND PRODUCTION METHODS OF THICK FILM GREEN SHEET AND ELECTRONIC DEVICE

摘要

A thick film green sheet slurry, a production method of thick film green sheet slurry, a production method of a thick film green sheet, a thick film green sheet and a production method of an electronic device are provided; by which coating of a relatively thick film becomes possible, a sheet formed after coating has excellent cutting property (strength capable of being cut), and a sheet having high air permeability, excellent handleability and a high adhesive force can be formed. In the present invention, a thick film green sheet slurry comprises a ceramic powder, a binder resin including a butyral based resin as the main component, and a solvent: wherein the solvent includes a good solvent for letting the binder resin dissolved well therein and a poor solvent having lower solubility to the binder resin comparing with that of the good solvent; and the poor solvent is included in a range of 30 to 60 wt % with respect to the entire solvent. The good solvent is alcohol, and the poor solvent may be toluene, xylene, mineral spirit, benzyl acetate, solvent naphtha, etc.
