    摘要: In accordance with the present invention, there are provided thermosetting resin compositions with a reduced propensity to shrink in volume upon cure and methods of use therefor. The compositions of the present invention include compounds having aromatic, rigid-rod like spacer groups between the crosslinkable moieties. As such, these compounds impart a degree of liquid crystal-like character to the thermosetting resin composition which results in lower shrinkage upon cure. This effect follows from the well-known expansion that occurs when liquid crystal-like materials pass from a nematic liquid crystal-like state to an isotropic state. Further provided by the present invention are low shrinkage die attach pastes and methods of use therefor.

    摘要: The present invention provides a thermoset conductive ink for use in through hole interconnections or similar electric and electronic applications to provide stable electrical connections. The conductive ink of this invention comprises a thermal curable resin system having an admixture of one or more maleimide, nadimide, or itaconimide containing resins, a comonomer and a catalyst, an electrically conductive material such as silver, copper or silver-coated copper, and optionally an organic solvent.
