Abstract
A resin having thermal conductivity comprises a styrene-butadiene-styrene block copolymer in 35 to 85 parts by weight, a styrene-ethylene-butene-styrene block copolymer in 5 to 65 parts by weight, a polyphenylene ether in 3 to 35 parts by weight; and a dendritic acrylate oligomer in 3 to 45 parts by weight. An adhesive layer and a circuit board using the resin composition are also described.
Claims11
A resin composition comprising:
- a styrene-butadiene-styrene block copolymer in 35 to 85 parts by weight;
- a styrene-ethylene-butene-styrene block copolymer in 5 to 65 parts by weight;
- a heat-conducting powder in 5 to 150 parts by weight;
- a polyphenylene ether in 3 to 35 parts by weight;
- and
- a dendritic acrylate oligomer in 3 to 45 parts by weight;
- wherein the heat-conducting powder is selected from a group consisting of aluminum trioxide, boron nitride, aluminum nitride, and any combination thereof.
An adhesive layer formed by curing a resin composition, the resin composition comprising:
- a styrene-butadiene-styrene block copolymer in 35 to 85 parts by weight;
- a styrene-ethylene-butene-styrene block copolymer in 5 to 65 parts by weight;
- a heat-conducting powder in 5 to 150 parts by weight;
- a polyphenylene ether in 3 to 35 parts by weight;
- and
- a dendritic acrylate oligomer in 3 to 45 parts by weight;
- wherein the heat-conducting powder is selected from a group consisting of aluminum trioxide, boron nitride, aluminum nitride, and any combination thereof.
A circuit board comprising at least one adhesive layer, each adhesive layer formed by curing a resin composition, the resin composition comprising:
- a styrene-butadiene-styrene block copolymer in 35 to 85 parts by weight;
- a styrene-ethylene-butene-styrene block copolymer in 5 to 65 parts by weight;
- a heat-conducting powder in 5 to 150 parts by weight;
- a polyphenylene ether in 3 to 35 parts by weight;
- and
- a dendritic acrylate oligomer in 3 to 45 parts by weight;
- wherein the heat-conducting powder is selected from a group consisting of aluminum trioxide, boron nitride, aluminum nitride, and any combination thereof.
