[PROBLEMS] To provide a method for forming a high-definition electroconductive thin line free from blurring at low cost.[MEANS FOR SOLVING PROBLEMS] A resin film having a hardness of 20 to 70, as measured by a type A measuring method specified in JIS K 6253, is formed on a surface of a resin base material. A thin line pattern is formed on the resin film using an electroconductive paste by intaglio printing or stencil printing or using an electroless plating catalyst ink by intaglio printing or stencil printing. Subsequently, a metal film is formed on the thin line pattern by plating to form an electroconductive thin line.

Abstract:
A high-reliability ceramic composite multilayer substrate that has excellent flatness and few remaining pores, can be produced at a low cost while simplifying the manufacturing process, and can eliminate layer separation or separation from a mother board. The ceramic composite multilayer substrate includes a laminate containing a first ceramic layer and a second ceramic layer that is disposed so as to contact the first ceramic layer and suppresses firing shrinkage in the plane direction of the first ceramic layer. The laminate includes a resin/ceramic composite layer in which porous ceramic is impregnated with a resin formed on at least one principal surface of the laminate.
Abstract:
A high frequency electronic part comprising a conductor wiring for transmitting an electric signal of 100 MHz to 100 GHz, and an insulation layer composed of a void containing thermoplastic resin film orientated in at least one direction by stretching. The void containing thermoplastic resin film contains voids in the range between 3% and 45% by volume, the number of voids in a thickness direction of the film is 5 or more, and a ratio of the number of voids to film thickness defined by the following equation is in the range between 0.1 and 10 voids/μm:ratio of the number of voids to film thickness (voids/μm)=the number of voids (voids) in film thickness direction/film thickness (μm).
Abstract:
A foamed bulk metallic glass electrical connection is formed on a substrate of an integrated circuit package. The foamed bulk metallic glass electrical connection exhibits a low modulus that resists cracking during shock and dynamic loading. The foamed bulk metallic glass electrical connection is used as a solder bump for communication between an integrated circuit device and external structures. A process of forming the foamed bulk metallic glass electrical connection includes mixing bulk metallic glass with a blowing agent.
Abstract:
Process for manufacturing an article comprising an approximately flat porous support and, within this support, defined zones in a chosen pattern, these zones being grafted with sensor molecules, such as metals, biological molecules, whereas the rest of the support remains free of this grafting.
Abstract:
A method of manufacturing an insulating sheet, a method of manufacturing a copper clad laminate, and a method of manufacturing a printed circuit board, as well as a printed circuit board manufactured using these methods are disclosed. The method of manufacturing an insulating sheet can include: forming a thermoplastic reinforcement material, which includes fibers secured by a thermoplastic polymer binder, and in which pores are formed; forming a thermoplastic resin layer such that the thermoplastic reinforcement material is impregnated with a thermoplastic resin; and hot pressing the thermoplastic reinforcement material and the thermoplastic resin layer. This method can be utilized to manufacture an insulating sheet, which has a low rate of moisture absorption and superb electrical properties, including a low dielectric constant (Dk) and low dielectric loss (Df), and in which the fibers can readily be impregnated with the resin.
Abstract:
An object of the present invention is to provide a method for manufacturing a porous material in which complicated and fine through portions, recessed portions, and the like have been patterned. It is to provide a patterned porous molded product or nonwoven fabric, in which a plated layer has been selectively formed on the surfaces of the through portions and the recessed portions.With the invention, a mask having through portions in a pattern is placed on at least one side of the porous molded product or the nonwoven fabric. A fluid or a fluid containing abrasive grains is sprayed from above the mask, thereby to form through portions or recessed portions, or both of them, to which the opening shape of each through portion of the mask has been transferred, in the porous molded product or the nonwoven fabric. The invention provides a porous molded product or a nonwoven fabric in which a plated layer has been selectively formed on the surfaces of the through portions or the recessed portions, or both of these, an electric circuit component, or the like.
Abstract:
A composite green sheet which comprises a green sheet including an inorganic powder and an organic binder, and a conductive layer formed thereon is prepared; the composite green sheet is then placed on a supporting surface of a base member containing a liquid; and the composite green sheet is irradiated with a laser light so as to form a through hole according to need, and thereby to evaporate the liquid contained in the base member so that waste remaining on the inner wall surface of the through hole is cleaned and removed. As a result, the conductive layer is exposed at the inner wall of the through hole penetrating the conductive layer.
