Abstract

An anisotropic conductive film (ACF) composition includes a binder having a thermoplastic resin and a styrene-acrylonitrile (SAN) copolymer resin, a curing composition, and conductive particles.

Claims (16)

1. An anisotropic conductive film (ACF) composition, comprising:

a binder including a thermoplastic resin and a styrene-acrylonitrile (SAN) copolymer resin;

a curing composition; and

conductive particles, wherein:

the curing composition includes:

at least one epoxy component, and

at least one heat curing agent.

2. The ACF composition as claimed in claim 1 , wherein:

the thermoplastic resin is in an amount of about 5 wt % to about 50 wt % by weight of the ACF composition,

the SAN copolymer resin is in an amount of about 5 wt % to about 50 wt % by weight of the ACF composition,

the epoxy component is in an amount of about 1 wt % to about 80 wt % by weight of the ACF composition,

the heat curing agent is in an amount of about 0.1 wt % to about 15 wt % by weight of the ACF composition; and

the conductive particles are in an amount of about 0.01 wt % to about 20 wt % by weight of the ACF composition.

3. The ACF composition as claimed in claim 1 , wherein the epoxy component includes one or more of a bisphenol epoxy, a novolac epoxy, a glycidyl epoxy, an aliphatic epoxy, and/or an alicyclic epoxy.

4. The ACF composition as claimed in claim 1 , wherein the epoxy component includes at least one or more of a solid-phase epoxy, a liquid-phase epoxy, and/or a soluble epoxy.

5. The ACF composition as claimed in claim 1 , wherein the heat curing agent includes one or more of an acid anhydride-based compound, an amine-based compound, an imidazole-based compound, and/or a hydrazide-based compound.
