Abstract:
Conductor-clad composites are advantageously fabricated using molding compounds and associated processing techniques. The conductive cladding is applied and bonded to the composite during the molding process. The conductor-clad composite may be used as printed wiring board, and in this embodiment results in improved physical, chemical, mechanical, and electrical properties.
Abstract:
An improved reinforced flexible printed wiring board is disclosed. The reinforcement in this printed wiring board is composed of a fabric woven from a yarn of plied continuous filaments of polyester and glass. The fabric is impregnated with an appropriate resin which is subsequently cured. This printed wiring board is found to have improved mechanical and thermal characteristics with little degradation in electrical properties.
Abstract:
A method of improving the dimensional and thermal stability of a fibrous web containing substrate is disclosed. A uniformly or randomly spun or bonded fabric or textile support is impregnated with a curable polymer resin, e.g., an epoxy-polyester resin. The impregnated resin is then fully cured whereupon a polymer resin coat is applied thereto. The coat is maintained in a partial cure state whereby a laminate comprising an internal woven or bonded fabric skeleton impregnated with a fully cured polymer resin and coated with a layer of a partially cured polymer resin is obtained.
Abstract:
A transparent conductive film (10) that has a substrate (14) having a surface (14a, 14b), a nanowire layer (12, 12a) over one or more portions of the surface (14a, 14b) of the substrate (14), and a conductive layer (16, 16a) on the portions comprising the nanowire layer (12, 12a), the conductive layer (16, 16a) comprising carbon nanotubes (CNT) and a binder.
Abstract:
The present invention relates to an extension structure of flexible substrates with conductive wires thereon. In a first embodiment, three flexible substrates are prepared, each having multiple conductive wires configured on their front surfaces. The third flexible substrate is flipped over, with its conductive wires facing downwards, and bonded across a boundary formed by the first and second flexible substrates. As a result, the corresponding conductive wires between the first and second flexible substrates are electrically coupled with each other through being physically pressed by corresponding conductive wires in the third flexible substrate.
