  • Patent number: 7617591
    Abstract: A method for fabricating the embedded thin film resistors of a printed circuit board is provided. The embedded thin film resistors are formed using a resistor layer built in the printed circuit board. Compared with conventional discrete resistors, embedded thin film resistors contribute to a smaller printed circuit board as the space for installing conventional resistors is saved, and better signal transmission speed and quality as the capacitive reactance effect caused by two connectors of the conventional resistors is avoided. The method for fabricating the embedded thin film resistors provided by the invention can be conducted using the process and equipment for conventional printed circuit boards and thereby saving the investment on new types of equipment. The method can be applied in the mass production of printed circuit boards and thereby reduce the manufacturing cost significantly.

  • Patent number: 7534527
    Abstract: Organic lithium salts suitable for use in electrolytes for primary or secondary rechargeable batteries include de-localized bulky anions over Lewis acid fragments, typically BF3, and organic moieties. The organic moieties may be, for example, anions derived from fused nitrogen heterocycles (e.g. benzeneimidate, benzitriazolate and the like); multi carboxylates (e.g. oxalate, 1,2,4,5-benzenetetracarboxylate and the like), and pyromellitic diimidate. The organic lithium salts of the invention have the general formula: Liq[Org(MXn)m], in which Org represents the organic moieties and MXn represents an organic or inorganic boron, aluminum or phosphorous containing Lewis acid.
