Title:
導電ペーストおよび導体膜の形成方法
Document Type and Number:
Japanese Patent JP7023042
Kind Code:
B2
Abstract:
To provide a conductive paste for gravure printing which can form a continuous thin conductor membrane suitable for internal electrodes of a small-sized high-capacity MLCC, and a method for forming the conductor membrane. In the conductive paste, viscosity x(Pa.s) and a contact angle y for a test surface having an arithmetic average roughness Ra of 0.010 ([mu]m) or less satisfy y < 17.6x+19.1 (where x ≤ 3.0 and y < 40); therefore, when gravure printing is performed on a ceramic green sheet using this conductive paste, the conductive paste is transferred promptly and uniformly from a gravure printing plate. Accordingly, the paste surface becomes smooth immediately after the transfer to make it easy for the film thickness to be thinned while maintaining continuity. Thus, it becomes possible to form a continuous conductor membrane having a thin film thickness suitable for internal electrodes of a small-sized high-capacity MLCC.
