Multi-layer cable design and method of manufacture
InactiveUS20080060832A1Economically manufacturedVolume/mass flow measurementFluid pressure measurement by electric/magnetic elementsCathodic arc depositionFiber
A novel method of designing and fabricating flexible and lightweight cable [100] having a central conductor [110], a dielectric layer [130], an outer conductor [150] and an insulation coating [170] using thin film technology is disclosed. The dielectric layer [130] is ‘grown’ on dielectric layer [130] using electrophoretic deposition to a specified thickness, based upon its intended use. It may include nano-diamonds. Ion beam assisted deposition is used to metalize the cable dielectric layer [130]. This may be ion beam assisted sputtering, ion beam assisted evaporative deposition or ion beam assisted cathodic arc deposition. In an alternative embodiment, the outer conductor may be etched to provide greater flexibility, or to add a piezoelectric layer. The central conductor [110] may be created from dielectric fibers [113] which are metalized as described above. The piezoelectric layer added to create ultrasonic transducer cables.

A coating of an encapsulated electrophoretic medium is formed on a substrate (106) by dispersing in a fluid (104) a plurality of electrophoretic capsules (102), contacting at least a portion of a substrate (106) with the fluid (104); and applying a potential difference between at least a part of the portion of the substrate (106) contacting the fluid (104) and a counter-electrode (110) in electrical contact with the fluid (104), thereby causing capsules (102) to be deposited upon at least part of the portion of the substrate (106) contacting the fluid (102). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps.

A method of using coated and / or magnetic particles to deposit structures including solder joints, bumps, vias, bond rings, and the like. The particles may be coated with a solderable material. For solder joints, after reflow the solder material may comprise unmelted particles in a matrix, thereby increasing the strength of the joint and decreasing the pitch of an array of joints. The particle and coating may form a higher melting point alloy, permitting multiple subsequent reflow steps. The particles and / or the coating may be magnetic. External magnetic fields may be applied during deposition to precisely control the particle loading and deposition location. Elements with incompatible electropotentials may thereby be electrodeposited in a single step. Using such fields permits the fill of high aspect ratio structures such as vias without requiring complete seed metallization of the structure. Also, a catalyst consisting of a magnetic particle coated with a catalytic material, optionally including an intermediate layer.

Method of printing variable information
The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.
