A conductive circuit containing a polymer composite, which contains at least one polymer and a modified graphite oxide material, containing thermally exfoliated graphite oxide having a surface area of from about 300 m.sup.2/g to 2600 m.sup.2/g, and a method of making the same.

Systems and methods for positioning a component on a surface or substrate including the steps of applying a coating to a selected deposit area of the surface, each deposit area defining at least a portion of a perimeter of an alignment area, depositing an fluid on the coating, and depositing, dropping, or otherwise positioning the component above the alignment area are disclosed.

The invention relates to an apparatus for the coating of a substrate, in particular of a circuit board, with a material application device for applying a coating material and with a gas supplying device for the supply of a gaseous medium, the material application device having an inner tubular element, the gas supply device having an outer tubular element which is arranged coaxially to the inner tubular element and surrounds the latter, so as to form between the outer and the inner tubular element a gas supply duct which has an annular orifice at one end, the supply duct being configured so that the gaseous medium flows out, parallel to the coating material, through the annular orifice, in order, when it impinges on the substrate, to displace the applied coating material and thereby distribute it over the area. The apparatus is distinguished in that the material application device has a jet valve which, in a first operating mode, carries out a jetted supply of material into the inner tubular element.

A coating can be provided on a substrate. Fabrication of the coating can include forming a solid layer in a specified region of the substrate while supporting the substrate in a coating system using a gas cushion. For example, a liquid coating can be printed over the specified region while the substrate is supported by the gas cushion. The substrate can be held for a specified duration after the printing the patterned liquid. The substrate can be conveyed to a treatment zone while supported using the gas cushion. The liquid coating can be treated to provide the solid layer including continuing to support the substrate using the gas cushion.

A circuit board with anti-corrosion properties, a method for manufacturing the circuit board, and an electronic device are provided. The circuit board includes a circuit substrate, a first protective layer, and a second protective layer. The circuit substrate includes a base layer and an outer wiring layer formed on the base layer. The circuit substrate further defines a via hole connected to the outer wiring layer. The first protective layer is formed on the outer wiring layer and an inner sidewall of the via hole, and is made of a white oil. The second protective layer is formed on the first protective layer.
