    摘要: A halogen-free dielectric resin mixture is described for use in microvia and other similar applications. The resin mixture contains a cyanate ester monomer or prepolymer a bismaleimide, an epoxy and a flame inhibiting compound selected from the group consisting of a phosphinic acid anhydride, a phosphonic acid andydride and a phosphonic acid half-ester. The flame inhibitor is present in an amount wherein the elemental phosphorus content is between about 2% and about 20% by weight, based on the weight of the resin mixture. The resin mixture can also include one or more coloring, fluorescent and UV absorbing agents. Prepregs based on the resin mixture with inorganic or organic reinforcing agents, as well as circuit boards and chip carriers made from the prepregs are also described. A resin coated article for use in microvia laser applications is likewise included.

    摘要: A method of forming a circuitized substrate for use in electronic packages. A substrate layer is provided that has a copper pad on a surface. A conductive seed layer and a photoresist layer are placed on the surface. The photoresist is developed and conductive material is placed within the developed features and a second conductive material placed on the first conductive material. The photoresist and conductive seed layer are removed to leave a micro-pillar array. The joining and lamination of two circuitized substrate layers utilizes the micro-pillar array for the electrical connection of the circuitized substrate layers.
