Abstract

A resin composition for molding includes an epoxy resin, a curing agent, and an inorganic filler containing at least one selected from the group consisting of calcium titanate particles and strontium titanate particles, in which a total content of the calcium titanate particles and the strontium titanate particles is 30% by volume or more and less than 60% by volume with respect to the entire inorganic filler.

Claims (62)

1 . A resin composition for molding, which is used in sealing of an electronic component in a high frequency device, comprising:

an epoxy resin;

a curing agent; and

an inorganic filler containing calcium titanate particles,

wherein a content of the calcium titanate particles is 30% by volume or more and less than 60% by volume with respect to the entire inorganic filler, and a total content of the calcium titanate particles and strontium titanate particles is 30% by volume or more and less than 60% by volume with respect to the entire inorganic filler, and

the inorganic filler further contains at least one selected from the group consisting of silica particles and alumina particles.

2 . The resin composition for molding according to claim 1 , wherein the curing agent includes an active ester compound.

3 . (canceled)

4 . The resin composition for molding according to claim 1 ,

wherein the inorganic filler contains alumina particles.

5 . The resin composition for molding according to claim 1 ,

wherein a relative dielectric constant of the entire inorganic filler at 10 GHz is 80 or less.

6 . The resin composition for molding according to claim 1 ,

wherein a total content of the inorganic filler is 40% by volume to 85% by volume with respect to the entire resin composition for molding.

7 . (canceled)

8 . The resin composition for molding according to claim 1 , which is used in an antenna-in-package.

9 . An electronic component apparatus comprising:

a support member;

an electronic component placed on the support member; and

a cured product of the resin composition for molding according to claim 1 which seals the electronic component.

10 . The electronic component apparatus according to claim 9 , wherein the electronic component includes an antenna.

11 . A resin composition for molding comprising:

an epoxy resin;

a curing agent; and

an inorganic filler containing calcium titanate particles, and a total content of the calcium titanate particles and strontium titanate particles is 30% by volume or more and less than 60% by volume with respect to the entire inorganic filler, wherein

the inorganic filler further contains at least one selected from the group consisting of silica particles and alumina particles, and

a total content of the inorganic filler is 40% by volume to 85% by volume with respect to the entire resin composition for molding.

12 . The resin composition for molding according to claim 11 , which is used in a high frequency device.

13 . The resin composition for molding according to claim 11 ,

wherein the curing agent includes an active ester compound.

14 . The resin composition for molding according to claim 11 ,

wherein the inorganic filler contains alumina particles.

15 . The resin composition for molding according to claim 11 ,

wherein a relative dielectric constant of the entire inorganic filler at 10 GHz is 80 or less.

16 . The resin composition for molding according to claim 11 , which is used in an antenna-in-package.

17 . An electronic component apparatus comprising:

a support member;

an electronic component placed on the support member; and

a cured product of the resin composition for molding according to claim 11 which seals the electronic component.

18 . The electronic component apparatus according to claim 17 ,

wherein the electronic component includes an antenna.

19 . A resin composition for molding comprising:

an epoxy resin;

a curing agent, including an active ester compound; and

an inorganic filler containing at least one selected from the group consisting of calcium titanate particles and strontium titanate particles,

wherein a total content of the calcium titanate particles and the strontium titanate particles is 30% by volume or more and less than 60% by volume with respect to the entire inorganic filler.

20 . The resin composition for molding according to claim 19 ,

wherein the inorganic filler further contains at least one selected from the group consisting of silica particles and alumina particles.

21 . The resin composition for molding according to claim 19 ,

wherein a total content of the inorganic filler is 40% by volume to 85% by volume with respect to the entire resin composition for molding.

22 . The resin composition for molding according to claim 19 , which is used in a high frequency device.

23 . The resin composition for molding according to claim 19 ,

wherein the inorganic filler contains alumina particles.

24 . The resin composition for molding according to claim 19 ,

wherein a relative dielectric constant of the entire inorganic filler at 10 GHz is 80 or less.

25 . The resin composition for molding according to claim 19 , which is used in an antenna-in-package.

26 . An electronic component apparatus comprising:

a support member;

an electronic component placed on the support member; and

a cured product of the resin composition for molding according to claim 19 which seals the electronic component.

27 . The electronic component apparatus according to claim 26 ,

wherein the electronic component includes an antenna.
