The invention discloses a manufacturing process of a vertical
ceramic patch
capacitor and a
capacitor product of the vertical
ceramic patch
capacitor, and belongs to the technical field of
microelectronics. The process comprises the steps of material preparation, in which raw materials are mixed according to a proportion;
coating, in which a layer of uniform paste thin film is formed from paste bya
coating machine; printing, in which internal
electrode paste is printed onto a
ceramic film by a
screen printing plate according to the process requirement; lamination, in which the printed ceramicfilms are laminated to form green blank having different
layers; lamination, in which the green blank is loaded in a lamination bag;
cutting, in which the laminated large green blank is
cut to relatively small blanks; gluing, in which the
cut blank blocks are glued;
sintering, in which the green blank is sintered to form a ceramic body; chamfering, corners of the product of the capacitor sinteredto form ceramic are chamfered; sealing, in which the product is sealed to form the ceramic body; and
sintering, in which the ceramic body is sintered to form the
ceramic capacitor. The purpose of changing the shape of the capacitor and the
electrode direction is achieved by changing an
electrode printing method, a
cutting method and a
coating process, so that the installation and the applicationof a capacitor in a flat
package component can be adapted.
