Abstract:
An organic montmorillonite enhanced epoxy resin and a preparation method thereof are provided. The preparation method of the organic montmorillonite enhanced epoxy resin includes adding an organic montmorillonite exfolicated by an organic solvent and a coupling agent to increase the thermal stability and reliability of the epoxy resin.
Abstract:
A printed circuit board structure includes a plurality of circuit layer plates stacked together in which each of the stacked circuit layer plates includes an epoxy resin plate body and a fabric structure completely encapsulated in the epoxy resin plate body, and each circuit layer plate stacked between two circuit layer plates is further provided with filler particles distributed in its epoxy resin plate body, and the two opposite and outermost circuit layer plates thereof have metal soldering pads on the outer surfaces of the epoxy resin plate body thereof, and the two opposite and outermost circuit layer plates do not have the filler particles in its epoxy resin plate body thereof.
