Abstract

A resin composition is provided. The resin composition includes a resin and an inorganic filler. The resin includes a bismaleimide resin and a polyphenylene ether resin. The inorganic filler includes a first inorganic filler and a second inorganic filler. An average particle size of the first inorganic filler is 0.3 μm to 0.6 μm. An average particle size of the second inorganic filler is 20 μm to 50 μm.

First claim

What is claimed is:

1 . A resin composition, comprising:
a resin comprising a bismaleimide resin and a polyphenylene ether resin; and an inorganic filler comprising a first inorganic filler and a second inorganic filler, wherein an average particle size of the first inorganic filler is 0.3 μm to 0.6 μm, an average particle size of the second inorganic filler is 20 μm to 50 μm, wherein a weight ratio of a usage amount of the first inorganic filler to a usage amount of the second inorganic filler is 1:1 to 1:3.

2 . The resin composition according to claim 1 , wherein the first inorganic filler is spherical silicon dioxide, the second inorganic filler is spherical boron nitride.

3 . The resin composition according to claim 1 , wherein the inorganic filler further includes a third inorganic filler, an average particle size of the third inorganic filler is between the average particle size of the first inorganic filler and the average particle size of the second inorganic filler.

4 . The resin composition according to claim 1 , wherein the inorganic filler further includes a third inorganic filler, an average particle size of the third inorganic filler is 4 μm to 6 μm.

5 . The resin composition according to claim 3 , wherein a weight ratio of a usage amount of the second inorganic filler to a usage amount of the third inorganic filler is 1:0.3 to 1:2.

6 . The resin composition according to claim 3 , wherein the third inorganic filler is spherical aluminium silicate.

7 . The resin composition according to claim 1 , wherein based on a total usage amount of 100 parts by weight of the resin, a usage amount of the inorganic filler is 100 parts by weight to 300 parts by weight.

8 . The resin composition according to claim 1 , wherein based on a total usage amount of 100 parts by weight of the resin, a usage amount of the bismaleimide resin is 30 parts by weight to 50 parts by weight, a usage amount of the polyphenylene ether resin is 30 parts by weight to 50 parts by weight.

9 . The resin composition according to claim 1 , wherein the resin further comprises a liquid rubber resin, a crosslinking agent or a combination thereof.

10 . The resin composition according to claim 9 , wherein based on a total usage amount of 100 parts by weight of the resin, a usage amount of the liquid rubber resin is 0 part by weight to 20 parts by weight, a usage amount of the crosslinking agent is 0 part by weight to 20 parts by weight.

11 . The resin composition according to claim 1 , further comprising a flame retardant, wherein based on a total usage amount of 100 parts by weight of the resin, a usage amount of the flame retardant is 5 parts by weight to 80 parts by weight.

12 . The resin composition according to claim 1 , further comprising a siloxane coupling agent, wherein based on a total usage amount of 100 parts by weight of the resin, a usage amount of the siloxane coupling agent is 0.1 parts by weight to 4 parts by weight.

13 . The resin composition according to claim 1 , wherein further comprising a catalyst, wherein based on a total usage amount of 100 parts by weight of the resin, a usage amount of the catalyst is 0.1 parts by weight to 2 parts by weight.

14 . The resin composition according to claim 4 , wherein a weight ratio of a usage amount of the second inorganic filler to a usage amount of the third inorganic filler is 1:0.3 to 1:2.

15 . The resin composition according to claim 4 , wherein the third inorganic filler is spherical aluminium silicate.
