20140308538 | SURFACE TREATED ALUMINUM FOIL FOR ELECTRONIC CIRCUITS - The surface of an aluminum substrate is modified to enhance the adhesion of the metal to polymeric materials. Intermediate layers, such as Zn/Sn, Co/Ni, and a Cu strike are applied before depositing a nodular Cu layer for bond enhancement. The surface treated aluminum substrate can be used in printed circuit boards, leadframes, or any electrical/electronic devices where Cu is typically used to reduce the cost and weight of the devices. | 10-16-2014 |
20140014239 | COPPER ALLOY CONTAINING COBALT, NICKEL AND SILICON - A process for manufacturing copper-nickel-silicon alloys includes the sequential steps of casting the copper alloy; hot working the cast copper-base alloy to effect a first reduction in cross-sectional area; solutionizing the cast copper-base alloy at a temperature and for a time effective to substantially form a single phase alloy; first age annealing the alloy at a temperature and for a time effective to precipitate an amount of a second phase effective to form a multi-phase alloy having silicides; cold working the multi-phase alloy to effect a second reduction in cross-sectional area; and second age annealing the multiphase alloy at a temperature and for a time effective to precipitate additional silicides thereby raising conductivity, wherein the second age annealing temperature is less than the first age annealing temperature. | 01-16-2014 |
