Abstract:
A ferrite circuit board includes a substrate and a wire. The substrate is made of ferrite and provided with a surface and an elongated groove recessed from the surface. The elongated groove has an inner wall having a roughness Ra ranging from 0.1 μm to 20 μm. The wire is embedded in the elongated groove of the substrate, such that the wire is not easily separated from the substrate. The ferrite circuit board can be used as an inductor to provide abundant functionality.
Abstract:
A touch sensing device includes a light-transmitting substrate, an edge layer and sensing lines. The light-transmitting substrate has an upper surface and a lower surface opposite to the upper surface, and the edge layer is covered on an edge of the upper surface of the light-transmitting substrate. The edge layer has a main body made of insulated material, and conductive wires. The main body has a first surface attached on the upper surface of the light-transmitting substrate, a second surface opposite and parallel to the first surface, and slots recessed downwardly from the second surface. The conductive wires are embedded in the slots, respectively. The sensing lines are disposed on the upper surface of the light-transmitting substrate and electrically connected with the conductive wires, respectively. Therefore, the touch sensing device can have simple and quick manufacturing process, high yield rate and low cost.
Abstract:
A ceramic circuit board includes a substrate made of Al2O3 or AlN and having an exterior surface and a groove recessed from the exterior surface. The groove has a bottom surface provided with a roughness Ra of 1-20 μm, a plurality of crests and a plurality of troughs. The crests are located in an imaginary plane separated from the exterior surface at a distance of 1-100 μm. An electro-conductive wire is embedded in the groove and has a top surface flush with the exterior surface. An LED package module includes a ceramic circuit board having two embedded electro-conductive wires, two bonding pads respectively mounted on the top surfaces of the wires, and an LED chip having two contacts electrically connected with the bonding pads respectively. The electro-conductive wire is connected with the substrate firmly and made relatively thicker capable of carrying a relatively larger electric current.
