保持性が不充分であった。When sealing chip-on-board etc. with sealant,
The shape retention of the sealant is important. This is because when a sealing material is applied to a bare chip from above, the sealing material must rise sufficiently so that the wires are not exposed. Conventionally, epoxy resin compositions have been widely used as encapsulants, and fillers and powdered curing agents are added to impart thixotropic properties and shape retention. There is. However, the shape retention was still insufficient.

はり好ましくない。In order to improve shape retention, it is possible to increase the filler ratio. However, doing so is not preferable because the viscosity of the sealing material increases considerably and the coefficient of linear expansion also changes. Although it is conceivable to increase the blending amount of the curing agent, this is still not preferable since the reactivity of the sealing material changes.

った。In order to achieve the above objects, the inventors conducted repeated research and came up with the idea of including a thixotropic agent in an epoxy resin composition. However, when a general organic thixotropic agent such as hydrogenated castor oil is used, although shape retention can be improved due to the thixotropic effect at room temperature,
It was found that the effect disappears at a curing temperature of 160°C.

うことを見出し、ここに、この発明を完成した。Furthermore, when hydrophilic silicon dioxide (Aerosil) was used, it was found that although the effect was large at the initial stage of addition, the effect almost disappeared after about a week. The inventor is
Further research was conducted. As a result, the use of hydrophobic silicon dioxide not only has a high effect at the initial stage of addition, but also
It was discovered that the effect is maintained even at 60°C and there is little change over time, and the present invention has now been completed.

A low molecular weight bisphenol A type epoxy resin or the like is used, but there is no particular limitation. Further, even a solid epoxy resin may be used as long as it is used in combination with a liquid epoxy resin so that the entire resin becomes liquid. Examples include phenol novolac type epoxy resins and cresol novolac type epoxy resins. Furthermore, in order to impart flexibility to the cured product, rubber-modified epoxy resins, alicyclic epoxy resins, etc. can also be used, and in order to impart flame retardance, various halogenated epoxy resins, etc. can also be used. .

A triazine-based curing agent such as riazine (hereinafter referred to as r2,4HTJ) is used. The amount of the epoxy curing agent to be used is determined as appropriate depending on the intended use of the epoxy resin composition, but in the case of the triazine curing agent, it is preferable to use 10 to 30 PHR based on the epoxy resin. The epoxy curing agent is preferably dispersed in an epoxy resin to form a single component.

It is preferable to add a small amount of 0.2 to 5.0% by weight, and usually about 0.5% by weight. Hydrophobic silica is silicon dioxide whose surface is methylated and has a reduced affinity for water. If the amount of hydrophobic silicon dioxide added is too large, the viscosity increases significantly and the surface condition of the cured product tends to become uneven, which is not preferable.

とおりである。Since the epoxy resin composition composition according to the present invention uses hydrophobic silicon dioxide, it is imparted with thixotropy and has very good shape retention, maintains its performance even at 160°C, and maintains its properties over time. There is little change and high shape retention lasts. Moreover, sufficient effects can be obtained even if the amount of silicon dioxide used is small; if the amount is small, the physical properties of the cured product will hardly change, and there will be no adverse effect on the linear thermal expansion coefficient or electrical properties. PCT (pressure hum test) and THB (thermal hum test)
There is no adverse effect on reliability tests such as epoxy resin, epoxy curing agent, filler, and thixotropic properties. After mixing the thixotropic agent with the filler, the mixture was kneaded with an epoxy resin in a planetary mixer while applying shear (shearing force) to obtain an epoxy resin composition. In the conventional example, an epoxy resin composition was obtained in the same manner as described above except that no thixotropic agent was used. However, as an epoxy resin, bisphenol A type epoxy resin (
YD127 (manufactured by Tobu Kasei), the latent hardener 2,4HT (manufactured by Nippon Hydrazine Kogyo) as the epoxy hardener, and fused silica (RD8 of Ryumori, average particle size 25 μm) as the filler. We decided to use each. The types of thixotropic agents used are shown in Table 1. As the hydrophobic silicon dioxide, hydrophobic Aerosil RY200 manufactured by Nippon Aerosil A- was used. The amount of fused silica added was 60% by weight. The amount of the thixotropic agent added is as shown in Table 1.

The height when 6g is dropped is 160° from the room temperature at the beginning of addition.
C 160 after curing and one month after adding thixotropic agent
It was decided to measure each case after curing at °C. Note that the surface state of the cured product will be a uniform surface if the epoxy resin composition is leveled flat, but if the thixotropy is too high, there will be no leveling and a rough surface.

On the other hand, Comparative Example 1 has poor shape retention at 160°C, large changes over time, and large increase in viscosity. Comparative Example 2 shows a large change in shape retention over time. In Comparative Example 3, the change in shape retention over time is large (and the increase in viscosity is also large).The conventional example has poor shape retention.
