約１０〜５０廂の厚さに通常形成される。(2) [Problem to be solved by the invention] It is known that the adhesion strength depends on the thickness of the binder layer 2 segregated on the surface of the green sheet 1 as shown in Fig. 2 (Fig. 3). ). That is, the green sheet consists of slurry, solvent, binder, plasticizer, etc.
For porcelain-thick green sheets, a binder layer 2 is usually formed on the surface to a thickness of about 10 to 50 feet.

される。The above-mentioned problem is solved according to the present invention in a method of applying a slurry to a polymer film of a carrier film and strengthening the adhesion of a green sheet by drying, characterized in that the initial drying temperature of the drying is 60°C to 70°C. This problem can be solved by a method of strengthening the adhesion of green sheets.

ンシートの破れや欠損を生ずる。(3) [Function] According to the present invention, the initial drying temperature of the green sheet is 60°C.
By setting the temperature in the range of ~70°C, the thickness of the binder layer on the surface of the green sheet can be controlled and optimum adhesion can be obtained. If the initial temperature is less than 60°C, the adhesion between the green sheet and the film becomes weak, causing the conventional problem, and if it exceeds 70°C, the adhesion is too strong and the green sheet breaks or breaks when peeled off.

。One part of alumina powder, one part of borosilicate glass, and one part of quartz glass are mixed, sized using a known ball mill, and kneaded.Methyl ethyl ketone (MBK), acetone solvent, acrylic resin binder such as PMMA, and dibutyl phthalate plasticizer are mixed. A slurry containing the above was prepared. Next, this slurry was applied to a defoaming device, pressure-fed, and applied to a molding machine. In the molding machine, the thickness was adjusted to about 300 mm using a doctor blade, and the initial drying temperature was set to 65°C.
Next, continuously increase the temperature to 70℃, 75℃, and 80℃ for about 1
It was dried at a speed of m/min. After drying, the thickness of the binder layer on the surface of the green sheet (the side to which the PET film was adhered) was measured and found to be approximately 50 JM. When this value was applied to FIG. 3, it had a high adhesion of 80 g/cm, and there were actually no problems in subsequent steps such as hole-drilling.
