摘要： A ceramic laminate, which is obtained by stacking ceramic green sheets provided with conductor films distributed on central portions along surface directions thereof, is charged in a die assembly. The die assembly includes an upper punch for pressing a first major surface of the ceramic laminate, a frame which encloses peripheries of the upper punch and the ceramic laminate, and a base plate for pressing a second major surface of the ceramic laminate in a manner opposite to the upper punch. In order to prevent the conductor films from undergoing misregistration toward peripheral edge portions of the ceramic laminate due to flowing of ceramic caused by a pressure difference between the portions provided with the conductor films and those not provided with conductor films, the upper punch is divided into an outer peripheral portion which comes into contact with the peripheral edge portions of the ceramic laminate and a body portion which comes into contact with its central portion. In a step of exerting pressure, the outer peripheral portion compresses the laminate to a higher degree than the body portion, so that a substantially homogeneous pressure is applied to the overall laminate.
摘要翻译：通过堆叠具有沿其表面方向分布在中心部分上的导体膜的陶瓷生片而获得的陶瓷层压体被装入模具组件中。模具组件包括用于挤压陶瓷层压体的第一主表面的上冲头，围绕上冲头和陶瓷层压体的周边的框架，以及用于以相反的方式挤压陶瓷层压板的第二主表面的基板到上冲。为了防止导体膜由于导体膜的部分与没有导体膜的部分之间的压力差导致的陶瓷流动而导致陶瓷层叠体的周边部分发生不对准，上冲头分为与陶瓷层叠体的周缘部接触的外周部和与其中心部接触的主体部。在施加压力的步骤中，外周部分将层压体压缩到比主体部分更高的程度，使得对整个层压体施加基本均匀的压力。
