    Abstract: A printed circuit board material for embedded passive devices, which has excellent electromagnetic properties and reliability is provided. The invention provides a printed circuit board material comprises: a conductive copper foil layer; a resin bonding layer formed on the conductive layer and including above 70-100 vol % of resin and 0-30 vol % of filler; and a functional layer formed on the resin bonding layer and including resin and filler. The printed circuit board material has the resin bonding layer interposed between the copper foil layer and the functional layer. Thus, even when the content of fillers in the functional layer is increased, the adhesion strength between the conductive layer and the functional layer is ensured without deteriorating the properties of the functional layer, such as dielectric and magnetic properties.

    Abstract: A thermoplastic or thermosetting B-stageable or pre-formed film underfill encapsulant composition that is used in the application of electronic components to substrates. The composition comprises a resin system comprising thermoplastic or thermally curable resin, an expandable microsphere, a solvent, and optionally a catalyst. Various other additives, such as adhesion promoters, flow additives and rheology modifiers may also be added as desired. The underfill encapsulant may be dried or B-staged to provide a coating on the substrate or component that is smooth and non-tacky. In an alternative embodiment, the underfill encapsulant is a pre-formed film. In both embodiments the expandable filler material expands upon the application of higher temperatures to form a closed-cell foam structure in the desired portion of the assembly.

    Abstract: Composite materials comprising at least 60 volume %, preferably 70 volume %, of particles of finely powdered filler material in a matrix of poly(arylene ether) polymer material are made by forming a mixture of the components, forming the required bodies therefrom, and then heating and pressing the bodies to a temperature sufficient to melt the polymer and to a pressure sufficient to disperse the melted polymer into the interstices between the filler particles. Surprisingly these polymer materials can only be effective as bonding materials when the solids content is as high as that specified, since with lower contents the resultant bodies are too friable. This is completely contrary to accepted prior art practice which considers that composites are progressivly weakened as the solids content is increased, so that such content must be limited. In processes to obtain as complete a dispersion of the components as possible they are individually dispersed in a liquid dispersion medium containing the polymer together with necessary additives, each mixture being ground if required to obtain a desired particle size, the mixtures are mixed, again ground to produce thorough dispersion, are separated from the liquid dispersion medium and green articles formed from the resulting pasty mixture. The green articles are then heated and pressed as described above. Mixtures of different filler materials may be used to tailor the electrical and physical properties of the final materials. The articles preferably comprise substrates for use in electronic circuits.

    Abstract: A method of abrading and simultaneously coating at least one surface of an article, particularly a circuit board assembly. The method comprises introducing abrasive particles into the compressed gas supply of a spray gun. The resulting gas stream with entrained abrasive particles is transported to and emitted from at least one spray nozzle of the spray gun where it is directed to the surface of the article with a film-forming coating composition stream also directed to and emitted from at least one nozzle of the spray gun. The abrasive particles can be simultaneously sprayed along with the optional coating composition onto the surface (these abrasive particles being microballoons in the case of a circuit board assembly). The surface is abraded while the coating is being applied. The resulting coating is substantially free of abrasive articles and has good adherence to the surface. The abrasive-containing compressed gas stream cleans and abrades the surface of the article, thereby preparing the surface to receive a coating.
