20100065314 | MULTI-LAYER CHIP CARRIER AND PROCESS FOR MAKING - Provided, are multi-layer chip carriers comprising an asymmetric cross-linked polymeric dielectric film, and processes for making the chip carriers. | 03-18-2010 |
20100288968 | COMPOSITE OF A POLYMER AND SURFACE MODIFIED HEXAGONAL BORON NITRIDE PARTICLES - Provided is a composite comprising a polymer and a plurality of surface-modified hexagonal boron nitride particles dispersed therewithin. Suitable polymers include polyimide and epoxy. A process is also provided. The surface modified hexagonal boron nitride particles comprise surface-bonded substituted phenyl radicals | 11-18-2010 |
20100291365 | FILM PREPARED FROM A CASTING COMPOSITION COMPRISING A POLYMER AND SURFACE MODIFIED HEXAGONAL BORON NITRIDE PARTICLES - Provided is a film having a thickness of less than 500 μm comprising a polymer and a plurality of surface-modified hexagonal boron nitride particles dispersed therewithin. The polymers can be polyimide or epoxy. A process for preparing the film by casting is provided. | 11-18-2010 |
20120178260 | MULTI-LAYER CHIP CARRIER AND PROCESS FOR MAKING - Provided are processes for making multi-layer chip carriers comprising an asymmetric cross-linked polymeric dielectric film. | 07-12-2012 |
20130153143 | METHOD FOR PREPARING CONSOLIDATED MULTI-LAYER ARTICLE USING CURABLE EPOXY COMPOSITION WITH QUATERNARY AMMONIUM BICARBONATE CURING CATALYST - Quaternary ammonium bicarbonates are suitable for use as catalysts in curable epoxy compositions. The curable compositions prepared therewith are used to prepare coated substrates, and to produce conformally sealed printed wiring boards and flexible circuits. Methods for preparation and curing are also provided. Of particular utility are compositions comprising benzytrimethyl ammonium bicarbonate. The curable composition is coated onto a first film or sheet, including a polyimide film or sheet. The coated sheet is then contacted to the surface of second film or sheet, where preferably there are discrete metallic conductive pathways disposed thereupon. | 06-20-2013 |
