Disclosed is a PCB including an embedded passive component and a method of fabricating the same. The PCB includes at least two circuit layers in which circuit patterns are formed. At least one insulating layer is interposed between the circuit layers. A pair of terminals is vertically formed through the insulating layers, plated with a first conductive material, and separated from each other by a predetermined distance. The embedded passive component is interposed between the terminals and has electrodes formed on both sides thereof. The electrodes are separated from the terminals by a predetermined distance and electrically connected to the terminals through a second conductive material.

Disclosed is a PCB including an embedded resistor and a method of fabricating the same. The PCB includes a plurality of circuit layers in which circuit patterns are formed. A plurality of insulating layers is each interposed between the circuit layers. The embedded resistor is made of a resistive material and received in a receiving hole formed in the plurality of circuit layers and the plurality of insulating layers such that walls defining the receiving hole extends from one of the circuit layers to another circuit layer. The receiving hole has a closed section, and a conductive material is plated on the opposite walls of the walls defining the receiving hole.

A method for manufacturing a substrate having a cavity is disclosed. The method comprises: (a) forming a barrier around a predetermined area where the cavity is to be formed on a copper foil laminated master, an internal circuit formed in the copper foil laminated master; (b) coating a thermosetting material in the area where the cavity is to be formed; (c) laminating a dielectric layer and a copper foil layer on the copper foil laminated master, on which the thermosetting material is coated; (d) pressing the laminated dielectric layer and copper foil layer using a press plate, on which a protruded part is formed in an area corresponding to the area where the cavity is to be formed; (e) forming an external circuit pattern in the upper part of the laminated dielectric layer; and (f) dissolving the coated thermosetting material using a solvent and forming the cavity. The method in accordance with the present invention can mount a plurality of integrated circuits by reducing the thickness of a substrate on a package on package.

A drum washing machine having an improved frame structure, the rigidity of which is reinforced. The drum washing machine includes side frames forming side surfaces thereof, where inclined planes are formed between front and upper surfaces of the side frames so that additional frames for reinforcing the rigidity of upper parts of the side frames are respectively connected to the upper surfaces of the side frames and upper regions of the front surfaces of the side frames. The drum washing machine further includes top brackets respectively connected to the upper surfaces, the inclined planes, and the upper regions of the front surfaces of the side frames for reinforcing the rigidity of upper parts of the side frames. The drum washing machine further includes a front frame, and a bottom panel or a top panel, connected to the side frames for reinforcing the rigidity of front, lower and upper parts of the side frames. The drum washing machine efficiently supports load increased according to large-scale and high-speed trends of the washing machine, and provides a frame structure capable of withstanding all loads without using a sheathing member, thus having various designs without limit.
