A fiber reinforced core panel is formed from strips of plastics foam helically wound with layers of rovings to form webs which may extend in a wave pattern or may intersect transverse webs. Hollow tubes may replace foam strips. Axial rovings cooperate with overlying helically wound rovings to form a beam or a column. Wound roving patterns may vary along strips for structural efficiency. Wound strips may alternate with spaced strips, and spacers between the strips enhance web buckling strength. Continuously wound rovings between spaced strips permit folding to form panels with reinforced edges. Continuously wound strips are helically wrapped to form annular structures, and composite panels may combine both thermoset and thermoplastic resins. Continuously wound strips or strip sections may be continuously fed either longitudinally or laterally into molding apparatus which may receive skin materials to form reinforced composite panels.

A metallic interconnect structure (200) for connecting a gold bump (205) and a copper pad (212), as used for example in semiconductor flip-chip assembly. A first region (207) of binary AuSn2 intermetallic is adjacent to the gold bump. A region (208) of binary AuSn4 intermetallic is adjacent to the first AuSn2 region. Then, a region (209) of binary gold-tin solid solution is adjacent to the AuSn4 region, and a second region (210) of binary AuSn2 intermetallic is adjacent to the solid solution region. The second AuSn2 region is adjacent to a nickel layer (213) (preferred thickness about 0.08 μm), which covers the copper pad. The nickel layer insures that the gold / tin intermetallics and solutions remain substantially free of copper and thus avoid ternary compounds, providing stabilized gold bump / solder connections.

The invention provide methods and materials for producing nutritious pet chews comprising an edible thermoplastic comprising from 45 to 80 wt. % starch selected from one or more potato and non-potato starches wherein said starch comprises at least 28% amylose as determined by size exclusion chromatography if less than 50% of said starch is potato starch or at least 20% amylose as determined by size exclusion chromatography if greater than or equal to 50% of said starch is potato starch; from 5 to 25 wt. % plasticizer; 2% to 15 wt % of a humectant and from 5 to 25 wt. % water.
