    摘要： A no-VOC or low-VOC no-clean flux formulation for use in the assembly of electronic circuit boards having a conformal coating. The formulation comprises a solvent, a water-soluble weak organic acid, a halide-free, non-ionic surfactant, and a biocidal co-solvent. The formulation is compatible with the conformal coating, permits no or low VOC emissions into the environment, and eliminates post-soldering cleaning steps.

    摘要： A microelectronic package includes a microelectronic element having contacts, a flexible substrate spaced from and overlying the microelectronic element and a plurality of conductive posts extending from the flexible substrate and projecting away from the microelectronic element. The conductive posts are electrically interconnected with the microelectronic element. Each conductive post has a conductive base that is in contact with the flexible substrate and a conductive tip that extends from the base, with the base of the conductive post having a larger diameter than the tip of the conductive post. In certain embodiments, the conductive base and the conductive tip have a cylindrical shape.

    摘要： By selecting different materials for each layer, a multi-layered electrode structure can be made with superior performance characteristics. For example, a multilayered electrode can include a high tensile strength tungsten core, a conductive intermediate palladium, palladium-nickel, or other platinum group metal layer for generating a corona discharge, and a hardened layer comprising rhodium or other platinum group metal or alloy of the same to resist frictional abrasion during removal of silica dendrites that accumulate on the electrode surface during operation.

    摘要： An apparatus for cleaning an emitter electrode in electrohydrodynamic fluid accelerator and precipitator devices via movement of a cleaning device including granular abrasives positioned to frictionally engage the emitter electrode. The cleaning device causes the granular abrasives to travel along a longitudinal extent of the emitter electrode to remove detrimental material accumulated on the electrode. The granular abrasives can be retained in housing, on opposed cleaning surfaces, and can be compressed by the housing or an applied force to abrade detrimental material from the electrode surface.

    摘要： A flux formulation without a surfactant is available for use in the assembly of electronic circuit boards as a no-clean formulation. The formulation includes a flux solution having a fluxing agent consisting essentially of one or more weak organic acids and a solvent consisting essentially of water. The flux solution serves to transport the fluxing agent before deposition thereof upon a soldering site for reliability improvement engendered by a lack of hygroscopic residue and for avoidance of environmental degradation engendered by a lack of volatile organic chemicals (VOC's). The method includes the steps of heating the flux solution and dispersing it as a fine spray.
