本発明は耐熱性に優れた電子部品封止用エポキシ樹脂成
形材料に関するものである。Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an epoxy resin molding material for encapsulating electronic components with excellent heat resistance.
従来、コイル、コンデンサ、トランジスタ、■Cなどの
電子部品封止用としては、エポキシ樹脂成形材料が広く
用いられている。特にガラス転移温度が高く、すなわち
耐熱性の優れた組成としては、フェノール類とホルムア
ルデヒドのノボラックをエポキシ化したエポキシ樹脂が
用いられており、その硬化剤としてはフェノール・ホル
ムアルデヒドノボラック樹脂が用いられている。Conventionally, epoxy resin molding materials have been widely used for encapsulating electronic components such as coils, capacitors, transistors, and C.

十分である。BACKGROUND ART Some electronic components such as transistors and ICs have an element temperature that increases due to the heat generated by the element. Additionally, there are heating processes such as solder dipping and solder reflow when mounted on a wiring board, and there are also products that perform high-temperature operation tests when screening electronic components. Considering this situation, molding materials for encapsulating electronic components must have a sufficiently high glass transition temperature (hereinafter referred to as Tg).
) is required. That is, the physical properties of the molding material change significantly after Tg, and for example, the coefficient of linear expansion becomes about three times as high as Tg or higher, resulting in large distortion between the element and the molding material. To reduce this distortion, the Tg of the molding material
There is a need to improve this, and the compositions of conventional molding materials are insufficient.

3,1972年)に記述がある。When n=0 in the above formula, the product number of benzene nuclei is 3,
In other words, there is only a trinuclear body (trifunctional epoxy resin), but
As n increases, the number of benzene products generated from phenols and hydroxybenzaldehyde increases at a ratio of 3+2n, and the actual epoxy resin is an aggregate of these. As a result of studies related to the present invention, it has become clear that in the epoxy resin (A) of the present invention, the larger the average number of benzene nuclei generated from phenols and hydroxybenzaldehyde, the more effective the Tg cycle is. There is. However, as the average product number of benzene nuclei increases,
This has the disadvantage that the softening point of the epoxy resin becomes high and the fluidity as a molding material decreases. Therefore, in order to fully exhibit the features of the present invention, the average number of benzene nuclei is preferably 4 or more and 10 or less. In this case, the average number of benzene nuclei can be determined from the molecular weight distribution measured by GPC (gel permeation chromatography). The GPC used in the present invention was Toyo Soda HLC801 model, and the column was TSK-Get (G-3000H, 1 column,

This is due to the structure of the epoxy resin. Conventionally, high Tg
Novolac type epoxy resins represented by the general formula are widely used as polyfunctional epoxy resins that are advantageous for chemical conversion [m is a positive integer]. Comparing this structure with the structure of the epoxy resin (A) of the present invention, the epoxy resin of the present invention has a structure in which a glycidoxyphenyl group is further added to the methylene carbon atom in the above formula, so the crosslinking density is becomes higher, and Tg becomes higher. Furthermore, by increasing the average number of benzene nuclei, the molecular weight of the epoxy resin (prepolymer) increases, and it is thought that the Tg after curing becomes even higher.
