Abstract: There is provided a multi-layered ceramic board and a method of manufacturing the same. A multi-layered ceramic board according to an aspect of the invention may include: an internal layer having a plurality of first dielectric sheets laminated, each of the first dielectric sheets prepared by mixing glass powder with a predetermined amount of alumina powder; and an external layer having at least one second dielectric sheet laminated on the surface of the internal layer, the second dielectric sheet prepared by mixing glass powder with alumina powder in a smaller amount than the first dielectric sheet, wherein via hole conductors and internal electrodes provided in the internal layer are electrically connected to a surface electrode provided on the surface of the external layer, and the internal layer, the external layer, the via hole conductors, the internal layer, and the surface electrode are fired at a predetermined temperature.

Abstract: There is provided a method of manufacturing a non-shrinkage ceramic substrate, and a non-shrinkage ceramic substrate using the same.

Abstract: Provided is a manufacturing method of a multi-layer ceramic substrate. The manufacturing method includes preparing an unsintered ceramic laminated body with a cavity, mounting a chip device within the cavity, filling the cavity, in which the chip device is mounted, with a ceramic slurry, attaching a constrained layer on top and/or bottom of the ceramic laminated body, and firing the ceramic laminated body. Accordingly, since the deformation of the cavity is prevented during the firing of the ceramic laminated body, the dimension precision and reliability of the multi-layer ceramic substrate can be improved.

Abstract: The present invention relates to a method of fabricating a printed circuit board having embedded multi-layer passive devices, and particularly, to a method of fabricating a printed circuit board having an embedded multi-layer capacitor, in which a capacitor is formed to have multiple layers in the PCB to increase capacitance.
