Conductive rubber material with laminated structure

Abstract

A laminated electrically conducting rubber material features that the electrically conducting particles are distributed onto the both surfaces of a high molecular rubber sheet for electric connection with the terminals on the drive package or glass substrate.

Description

technical field [0001] The invention relates to a layered conductive adhesive material, in particular to a layered conductive adhesive material formed by spreading conductive particles on the surface of a sheet-shaped polymer adhesive material. Background technique [0002] The bonding part of the glass panel of the traditional liquid crystal display and the driving component generally adopts the conductive material of conductive particles (spherical particles) for electrical conduction, such as Figure 1A As shown in 1C, the method is to coat or attach the anisotropic conductive material 3 on the terminal 2 of the glass substrate 1 of the liquid crystal display, and then connect the metal terminal 5 on the driving component 4 to the terminal 2 on the glass substrate 1 of the liquid crystal display. Alignment bonding completes electrical conduction. The above-mentioned electrical conduction generally produces electrical conduction in the Z-axis direction but insulates in the...

AI Technical Summary

Problems solved by technology

The smaller size of conductive particles will not only increase the production cost and increase the difficulty of particle manufacturing, but also the surface roughness of the terminal will limit the development of particle size

When the particle size is smaller than the surface roughness of the terminal, it will cause poor electrical conduction

And when the density of the conductive particles 31 increases, although the connection resistance can be reduced, it cannot meet the requirements of fine-pitch adhesion.
