The mainstream is resin encapsulation by low-pressure transfer molding using epoxy resin, which has advantages in terms of mass production and cost as well as improved reliability.

ジにクラックが生じる。For example, in a surface-mounting device, the device itself is directly immersed in solder at the time of mounting, and is rapidly exposed to a high temperature and harsh environment, so that a package crack is inevitable. That is, moisture absorbed during storage after molding abruptly vaporizes and expands when exposed to high temperatures, and the sealing resin cannot withstand this and cracks occur in the package.

The improvement of moisture absorption resistance to solder cracking is not yet satisfactory.

成物を提供する。(Means for Solving the Problems) The present invention is to solve the above problems, and the following components (A) an epoxy resin having a biphenyl skeleton to which an aminosilicone is added, a vinylsilicone is radicalized by a peroxide. There is provided an epoxy resin composition for encapsulation, which comprises an addition-polymerized biphenyl type epoxy resin, (B) a curing agent (C), a curing accelerator (D) and an inorganic filler.

することができる。The biphenyl type epoxy resin to which the aminosilicone as the component (A) in this composition is added is a resin of a compound having a biphenyl skeleton together with an epoxy group in one molecule, for example, (N is a number from 0 to 5), a biphenyl type epoxy resin or a mixed resin thereof, or a polyhydric phenol having an average number of hydroxyl groups in one molecule of 2.3 to 10 is added to each phenol group per phenol group. It is possible to use an epoxy resin that is reacted at a ratio of 0.05 to 0.6 hydroxyl groups.

It is about 3,000 as appropriate.

形、使用時の条件等に応じて選択することができる。Of course, with respect to the chemical structures of the above epoxy resins and aminosilicones, various kinds can be used as long as they meet the essential requirements such as biphenyl skeleton, and are selected according to the molding conditions of the sealing resin, the conditions of use, etc. can do.

ル付加重合させて組成物に配合する。However, with only the aminosilicone-added biphenyl type epoxy resin, the strength of the encapsulating resin is greatly reduced, and the moisture absorption solder crack resistance is poor. Therefore, in this invention, vinyl silicone is radically addition-polymerized with the above epoxy resin in the presence of a peroxide to be blended in the composition.

には、ドメインとマトリックスとの間に化学的結合を持
たないため、機械強度の低下防止効果には限界がある。When only vinyl silicone used in the component (A) of the present invention is radically added to an epoxy resin, the particle size of the silicone domain is very large from the viewpoint of compatibility, the stress reducing effect is reduced, and Poor adhesion to the matrix reduces mechanical strength. It is possible to reduce the domain diameter and improve the adhesion to the matrix by using various compatibilizers such as polyether modified silicone, but in this case, between the domains and the matrix. Since it has no chemical bond, there is a limit to the effect of preventing reduction in mechanical strength.
また、ポリエーテルシリコーンなどの相溶化剤は吸湿性
が高く、耐吸湿クラック性という観点からは不利であ
る。Further, a compatibilizing agent such as polyether silicone has high hygroscopicity, which is disadvantageous from the viewpoint of resistance to moisture absorption cracking.

る。However, the above problems are solved by the component (A) of the present invention. That is, the aminosilicone-added epoxy resin has the property as a compatibilizer, the domain diameter of the vinylsilicone radical addition polymer is reduced, and it occurs with the chemical bond between the domain and the matrix, that is, the addition of vinyl groups to each other. Because of the bond formed by the reaction between the methyl group of amino silicone and the vinyl group, the stress can be reduced with a small decrease in mechanical strength. Entangled as a crosslinked structure, it is considered to have a unique effect. The vinyl silicone in this case is also made of organopolysiloxane having a vinyl group.

くなる。From these viewpoints, the weight ratio of the component (A) as a silicone component is usually preferably about 1/4 to 2/1 of aminosilicone / vinylsilicone. If it is less than 1/4, the compatibilizing effect becomes small and the domain particle size becomes large. On the other hand, if it is larger than 2/1, the effect of aminosilicone becomes large and the strength is greatly reduced.

There is no particular limitation on the type of the effect accelerator of the component (C) to be blended therein, and one or more effect accelerators such as phosphorus-based, tertiary amine-based, or imidazole-based effect accelerators can be used. .
