  • Patent number: 5534092
    Abstract: In order to suppress deviation of conductor films and to effectively remove voids when a laminate obtained by stacking a plurality of ceramic green sheets provided with the conductor films is pressed in the direction of stacking, a pressing step is divided into a preliminary pressing step and a main pressing step which is carried out subsequently thereto. In the preliminary pressing step, a temperature of at least 40.degree. C. is applied to the laminate of the plurality of ceramic green sheets by a heater, while a press head is driven toward the laminate, thereby applying a pressure of not more than 50 kgf/cm.sup.2 to the same. The preliminary pressing step may be further divided into first and second preliminary pressing steps. In the first preliminary pressing step, the laminate is pressed by a press surface having projections on regions corresponding to those provided with the conductor films, so that voids are removed from the regions provided with the conductor films.

  • Patent number: 5503726
    Abstract: A plating apparatus (11) includes a plating solution container (13) storing a plating solution (14) and a cathode (18) dipped therein, for plating objects which are placed on the cathode (18) by driving an air cylinder (22) for applying vibration to the cathode (18) while making a stopper (24) collide with a forward end (21a) of a coupling member (21) which is coupled to the air cylinder (22) and the cathode (18) thereby applying an impact to the cathode (18).
