    • A laminated ceramic device formed by laminating ceramics and conductive metals having a conductor section at a part of at least one of its upper and lower surfaces, in which the difference in level between the conductor section and the section other than the conductor section is smaller than the thickness of the conductor section. Consequently, even in the case of arranging the pattern conductors on both the upper and the lower surfaces of the device, a laminated ceramic device can be obtained in which pattern conductors can be arranged with high accuracy at low cost, no special care is required in the case of polishing, and the thickness accuracy and the bond strength of electrodes are high.

    • The invention related to a paste for via hole filling which enables inner via hole connection between electrode layers without employing through hole plating techniques, and a multi-layered printed circuit board using the same. The conductive paste composition of the invention comprises a) 70-90 wt % of copper particles of an average particle size of 0.5-8 .mu.m; b) 0.5-15 wt % of insulating particles of an average particle size of 8-20 .mu.m; and, c) 6-17 wt % of heat setting type liquid epoxy resin, in order to exhibit low viscosity and low volatility. The conductive paste is printed and filled into through holes passing through a laminated substrate which is provide with copper foils on both sides thereof, to form a printed circuit board in which the via holes are electrically connected after thermosetting. By adding insulating particles of large particle size, the amount of copper particles to be added is decreased so that a via hole connection of low specific resistance and high reliability is obtained, and improvements in a decrease of viscosity and continuous printability of the paste itself can be achieved.
    • 本发明涉及一种用于通孔填充的糊剂,其能够在不使用通孔电镀技术的情况下实现电极层之间的内部通孔连接,以及使用该糊状物的多层印刷电路板。 本发明的导电糊组合物包含a)70-90重量%的平均粒径为0.5-8μm的铜颗粒; b)0.5-15重量%的平均粒径为8-20μm的绝缘颗粒; 和c)6-17重量%的热固定型液体环氧树脂,以显示低粘度和低挥发性。 将导电性糊料印刷填充到通过其两侧设置有铜箔的层叠基板的通孔中,形成印刷电路基板,其中通孔在热固化后电连接。 通过添加大粒径的绝缘粒子,可以减少添加的铜粒子的量,从而获得低电阻率和高可靠性的通孔连接,并且可以提高糊剂本身的粘度和连续印刷性的降低 实现。
