れるグリーンシートの積層方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for laminating green sheets used in manufacturing ceramic multilayer wiring boards and the like.
従来の技術
従来、グリーンシートの積層方法としては、重ねられた
複数枚のグリーンシートに、温度が約８０℃〜１２０℃

ｒＡの条件で、プレス機によって熱圧着を行っていた。Conventional technology Conventionally, as a method for laminating green sheets, multiple stacked green sheets are stacked at a temperature of approximately 80°C to 120°C.
, pressure force approximately 1s o Kg/crA ~ 26oKq/c
Thermocompression bonding was performed using a press machine under rA conditions.

ートの積層方法を提供するものである。'I-g/crA has the disadvantage that the pressing machine becomes very large as the size of the green sheets to be laminated increases, and thermocompression bonding alone is not suitable for laminating conditions during lamination. Due to the variation, the lamination becomes insufficient, and when the laminated green sheets are fired, separation between the layers called delamination may occur. The present invention provides a method for laminating green sheets, which makes it possible to miniaturize the press machine and reliably integrate green sheets into one.

The organic component in the green sheet, the binder, is activated,
In addition, as the binder rubs against each other at the interface between the green sheets, the pressure to be applied is reduced, for example, compared to conventional 16

。EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. As shown in the drawing, a mold 2b with a built-in ultrasonic oscillator 4 and a heater 3 is placed on the base 6 of a press, and plastic films 6a and 6b whose surfaces are coated with silicon are placed on the mold 2b. Several green sheets 1 to be stacked are placed between the two, and then the mold 2a containing the heater 3 is lowered to apply weight.

When applying 00KV Fuku for 2 minutes, the stacked green sheets appeared to be integrated, but when I peeled off each green sheet with tweezers, I found that
peeled off easily. As a second condition, molds 2a and 2b
The temperature of the whole leopard is 80℃, and the output of ultrasonic oscillator 4 is 200W (
The operating state was set at a frequency of 28 k) h) and a pressure of 20 K.
When y/ad was applied for 2 minutes, the stacked green sheets were completely integrated, and even if one tried to peel off one of the green sheets with a bin set, it could not be peeled off. Various experiments were conducted by changing the output and frequency of the ultrasonic oscillator 4, and the bundling output was 2ooW to 2KW, and the frequency was 28Kh to s.
北で良好な結果が得られた。Good results were obtained in the north.
