    • A molding resin composition containing, in a resin, a filler comprising a globular powder of which mean particle diameter is not smaller than 0.1 .mu.m and not greater than 1.5 .mu.m (x component), a globular powder of which mean particle diameter is not smaller than 2 .mu.m and not greater than 15 .mu.m (y component) and a globular powder of which mean particle diameter is not smaller than 20 .mu.m and not greater than 70 .mu.m (z component), wherein proportions of the x, y and z components based on the total volume of x, y and z components are not smaller than 10% by volume and not greater than 24% by volume, not smaller than 0.1% by volume and not greater than 36% by volume and not smaller than 57% by volume and not greater than 76% by volume, exhibits an excellent fluidity even when loaded with a high percentage of filler. Further, their cured products are lowered in the moisture absorption and thermal expansion coefficient of which increases result from the resin itself present in the cured product. Further, a semi-conductor package sealed with the resin composition exhibits a high package crack resistance. The resin composition is suitable for use as a sealing material for semi-conductors, and extensively applicable to other uses requiring a high-percentage loading of filler.
    • 一种成型树脂组合物,其在树脂中含有平均粒径不小于0.1μm且不大于1.5μm(x组分)的球状粉末的填料,其平均粒径不为球状粉末 小于2μm,不大于15μm(y成分)和平均粒径不小于20μm且不大于70μm(z成分)的球状粉末,其中x, 基于x,y和z成分的总体积的y和z成分不小于体积的10体积%且不大于24体积%,不小于体积的0.1体积%且不大于36体积% 小于57体积%且不大于76体积%,即使在加载高比例填料时也具有优异的流动性。 此外,由于固化物中存在的树脂本身,其固化物的吸湿性和热膨胀系数增加,其固化产物降低。 此外,用树脂组合物密封的半导体封装具有高封装抗裂性。 该树脂组合物适合用作半导体的密封材料,并且广泛适用于需要高填料填充量的其它用途。
