Abstract: A multiple layered apparatus and method for forming a z-axis interconnect is provided. The multiple layered apparatus comprises a protective layer, a dielectric layer, a conductive layer, and a support layer. A method for forming a z-axis interconnect using the multiple layer apparatus resulting in a thinner and less expensive structure for printed circuit board applications.

Abstract: Magnesium oxychloride cement compositions, products, and uses thereof, are provided by mixing magnesium oxide, a magnesium chloride solution, and aggregate particles. The cement compositions are adapted for use in repairing damaged concrete surfaces, casting both functional and decorative forms, and coating surfaces with stucco. The addition of a small amount of acid to the cement composition promotes a more complete cementing reaction. The resulting cement product exhibits substantially increased strength and water resistance. Brine from the Great Salt Lake is a preferable source of the magnesium chloride solution. Brine from the Great Salt Lake results in a cement composition substantially stronger than cement produced from a pure magnesium chloride solution. Use of the Great Salt Lake brine as the gauging solution in lieu of a gauging solution made from magnesium chloride flakes (hexahydrate) reduces manufacturing costs of magnesium oxychloride cement products.
