    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.

    Abstract: A method of making a light-guiding module includes the steps of applying a layer of light guide material containing methyl methacrylate oligomers on a reflector, and polymerizing the methyl methacrylate oligomers of the light guide material at a temperature ranging from 60 to 65° C. for 2.5 to 3 hours to form a light guide plate containing polymethylmethacrylate and integrally combining the reflector. Since there is no any gap between the light guide plate and the reflector, the light-guiding module reduces light loss, and improves the luminous efficiency of the backlight unit in which the light-guiding module is used.

    Abstract: A package structure includes a lead frame, an insulator, a plurality of conductive vias, a patterned metal layer, and a chip. The lead frame includes a plurality of contacts. The insulator covers the lead frame. The conductive vias are disposed on the insulator and connected to the contacts. The patterned metal layer covers an outer surface of the insulator and includes a groove and a circuit portion. The circuit portion is connected to and covers the conductive vias and contacts. The groove surrounds the circuit portion such that the circuit portion is electrically insulated from the rest of the patterned metal layer. A surface of the insulator exposed by the groove is lower than the outer surface. The chip is disposed on the insulator and electrically connected to the circuit portion.

    Abstract: The invention provides an electrical connector and a backlight module using that electrical connector. The electrical connector includes a body and two conducting lines. The body is provided with first and second connecting portions, the former of which has a first connecting surface and the latter has a second connecting surface. An invariable relative angle is defined between the first and second connecting surfaces. The conducting lines are coated on the first and second connecting surfaces without crossing each other. The backlight module includes a light guide plate, two LED light bars mounted to two respective light receiving edges of the light guide plate, and an aforesaid electrical connector connecting the LED light bars. The electrical connector is electrically connected with the LED light bars and fixes their relative positions. Besides, it is easy to install the electrical connector to connect the LED light bars firmly.
