摘要:
Shielded cable devices are formed of a conductive loaded resin-based material. Non-insulated conductors with shields, coaxial shielded cables, twisted pair shielded cables, and multi-wire shielded cables are described. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The ratio of the weight of the conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers to the weight of the base resin host is between about 0.20 and 0.40. The micron conductive powders are formed from non-metals, such as carbon, graphite, that may also be metallic plated, or the like, or from metals such as stainless steel, nickel, copper, silver, that may also be metallic plated, or the like, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, or the like. The conductive loaded resin-based conductive shield of the shielded cable devices can be formed using methods such as injection molding compression molding or extrusion. The conductive loaded resin-based material used to form the conductive shield of the shield cable devices can also be in the form of a thin flexible woven fabric that can readily be cut to the desired shape.
摘要:
A wired circuit board which even when a conductive pattern is formed in the form of fine pitch can provide improved adhesion between the conductive pattern and an insulating layer to prevent a plating solution from remaining between a metal plating layer and the insulating layer, so as to prevent ionic impurities in the plating solution from remaining as residual or ionic contamination, whereby even when electric current flows through the circuit under a high temperature and high humidity environment over a long term, a short circuit from ionic migration can be prevented to suppress insulating failure. Lower end portions of terminal portions 5 formed on an insulating base layer 2 and lower end portions of side surfaces and metal plating layers 6 covering over the terminal portions 5 are embedded in the insulating base layer 2 in a flexible wired circuit board 1 at one longitudinal end portion thereof exposed from an insulating cover layer 4. This can provide the result of preventing infiltration of the plating solution in between the metal plating layers 6 and the insulating base layer 2 when the metal plating layer 6 is formed.

摘要:
In the step of forming an external connection electrode, at one end of each ink chamber (26), conductive resin (10) is applied into a plurality of ink chambers (26) and onto a plurality of protruding surfaces of a piezoelectric substrate (60) so as to form a single straight line to vertical intersect the direction of extension of the ink chambers (26). After this, abrasive finishing or grinding is performed to remove the conductive resin (10) from the protruding surfaces of the ink chamber walls. As a result, the conductive resin (10) filling inside the ink chamber (26) constitutes an electrode for an external connection. This reduces the electrostatic capacity attributed to the piezoelectric substrate. Moreover, it is possible to increase the ink jet head drive frequency. This reduces power consumption and provides an ink jet head having a high productivity and reliability and capable of high-speed printing as well as its manufacturing method.
