摘要:
Disclosed is a microfine structure which can be used as an anisotropic conductive member. Also disclosed is a method for producing such a microfine structure. Specifically disclosed is a microfine structure which is composed of a base having penetrating micropores at a density of not less than 10,000,000 micropores/mm 2 . In this microfine structure, some penetrating micropores are filled with a substance other than the material of the base.
摘要:
This silver-coated spherical resin includes: a spherical resin; and silver coated on a surface of the spherical resin, wherein an amount of the silver is in a range of 2 to 80 parts by mass with respect to 100 parts by mass of the silver-coated spherical resin, and a crystallite diameter of the silver measured by X-ray diffractometry is in a range of 18 to 24 nm. This method for producing a silver-coated spherical resin includes: a process of subjecting a spherical resin to a pretreatment using an aqueous solution of a tin compound; and a subsequent process of subjecting the spherical resin to an electroless silver plating using a reducing agent, wherein, during the pretreatment, a temperature of the aqueous solution of the tin compound is set to be in a range of 20 to 45°C.
摘要:
To provide a curable resin composition that can improve resistant properties such as thermal impact resistance even in a high-temperature and high-humidity environment and has a high adhesive property, high conduction reliability and superior crack resistant property. The curable resin composition contains an epoxy resin and an epoxy resin-use curing agent, and is characterized in that a difference between a maximum value of tan δ in a viscoelastic spectrum and a value of the tan δ at -40°C thereof is 0.1 or more.

Provided is a method for manufacturing an electronic component using a conductive film formed by layering an adhesive layer and a release layer. The method for manufacturing the electronic component having a wiring includes: disposing an adhesive film formed by layering an adhesive layer and a release layer above a substrate having a surface on which a wiring is formed, such that the adhesive layer faces the surface; cutting the adhesive layer by inserting the wiring into the adhesive layer by depressing the adhesive film to the substrate; separating one adhesive layer portion of the cut adhesive layer from the surface; and releasing the release layer from the other adhesive layer portion of the cut adhesive layer.
