Connection structural body and electronic part

Abstract

The invention relates to a connection structural body and an electronic part. The conductive connection strucrtual body having advantages of excellent anti-voltage performance and ability of maintaining conductivity, and the electronic part of the connection structural connection body are provided. The connection structural body is characterized in that the anisotropic conductive connectionstructual body having a member having a first electrode and a member having a second electrode, which are electrically connected together by conductive materials comprising conductive particles in a bonding agent layer, and the bonding agent layer comprising the conductive particles in a concentration of 0.01 - 4.0 vol5; the film thickness of the bonding agent layer of the electric connectin part between the first electrode and the second electrode is lower than a half of the maximum particle diameter of the conductive particles, and the film thickness of the bonding agent layer of the non-electric connection part is more than the above mentioned maximum particle diameter of the conductive particles.

Description

technical field [0001] The present invention relates to an anisotropic conductive connection structure and an electronic component in which a first electrode and a second electrode are electrically connected in an adhesive layer. Background technique [0002] With the increase in the density of printed circuit boards brought about by the reduction in weight and size of electronic equipment in recent years, as electrical connections for electronic components, such as electrical connections between circuit boards and electronic components, and electrical connections between circuit boards, technology, the development and improvement of conductive adhesives have been promoted (for example, Patent Documents 1 and 2). The conductive adhesive can be electrically connected in a light-weight and space-saving manner by applying the conductive adhesive between members to be electrically connected and performing thermocompression bonding. [0003] The conductive adhesive itself is ins...

AI Technical Summary

Problems solved by technology

[0003] The conductive adhesive itself is insulative, but the conductive particles contained in the conductive adhesive are clamped between electrodes and pressed to form a conductive path by thermocompression bonding, thereby making the electrical connection between the components become possible
