    摘要: A method for manufacturing a printed circuit board of a backlight module is provided. The printed circuit board includes a light bar region and a heat dissipating region. The light bar region used for mounting a light bar of the backlight module and formed with a conductive circuit for supplying power for the light bar. The heat dissipating region is connected with the light bar region. A connection location of the light bar region and the heat dissipating region is subjected to cutting to form a slot located at a side of the printed circuit board in order to prevent short-circuiting between the heat dissipating region and the conductive circuit of the light bar region. The cutting is made to partly penetrate through the thickness of a dielectric layer on which the conductive circuit is formed in order to completely separate the light bar region from the heat dissipating region.

    摘要: A noise dampening energy efficient circuit board includes a carbon material layer for dampening electromagnetic interference between surface mount components and trace patterns of the circuit board. One or more ground plane layers are arranged relative to the carbon material layer to cooperatively dampen and repel noise of varying frequencies. The positioning of the carbon material layer with respect to the ground plane layer enhances the ground plane operation. Glass fiber material layers and other insulating dielectric layers are disposed at particular locations within the noise dampening energy efficient circuit board. The carbon material layer and the ground plane layer dampen electromagnetic noise, thereby permitting energy saving design considerations, increasing energy efficiencies and reducing power consumption. Mounting posts of the surface mount components include insulating sleeves to selectively insulate different layers of the circuit board from surface mount components. Methods for constructing and using the circuit board are also disclosed.

    摘要: An electrical circuit with large creepage isolation distances is provided. In some embodiments, the electrical circuit is capable of increasing creepage isolation distances by many multiples over traditional electrical circuits. In one embodiment, an electrical circuit comprises a ground circuit optically coupled to a floating circuit, and an isolated circuit optically coupled to the floating circuit. The circuits can be optically coupled with opto-isolators, for example. The isolated circuit can have a creepage isolation distance at least twice as large as a traditional circuit. In some embodiments, “n” number of floating circuits can be optically coupled between the ground circuit and the isolated circuit to increase the total creepage isolation distance by a factor of “n”. Methods of use are also described.

    摘要: A method for manufacturing a printed circuit board enables a metal residue between wirings to be removed inexpensively without side etching of a copper layer while having sufficient insulation reliability for micro wiring working. The method includes forming a base metal layer directly at least on one face of an insulator film without an adhesive, and a copper coat layer formed on the base metal layer to form adhesiveless copper clad laminates, then forming a pattern on the adhesiveless copper clad laminates by an etching method. The etching method includes a process of etching treatment for the adhesiveless copper clad laminates with an iron (III) chloride solution or a copper (II) chloride solution containing hydrochloric acid and then, a process of treatment with an acid oxidant containing permanganate and acetic acid.
