    摘要: An epoxy resin composition comprising: (A) an epoxy resin having at least three epoxy groups per molecule and an epoxy equivalent of 170 or lower; (B) an epoxy resin having a phenolic nucleus and two epoxy groups in such an amount that a weight ratio of the epoxy resin (B) to the epoxy resin (A) ranges from 35/65 to 65/35; (C) a phenolic curing agent in such an amount that a molar ratio of phenolic hydroxyl groups to the whole epoxy groups in the composition ranges from 0.5 to 1.5; and (D) an inorganic filler in an amount of from 86 to 92 wt %, based on a total weight of the composition. The composition provides encapsulated semiconductor devices much less warped than those encapsulated with a conventional composition.

    摘要: An epoxy resin composition comprising (A) at least one epoxy resin comprising (a) a naphthalene ring-containing epoxy resin having at least one substituted or unsubstituted naphthalene ring in a molecule and having an epoxy equivalent of 175 to 210, (B) a phenolic resin having at least one substituted or unsubstituted naphthalene ring in a molecule, and (C) an inorganic filler, the substituted or unsubstituted naphthalene ring of the epoxy resin (a) being contained in an amount of 45 to 60% by weight in the total amount of the epoxy resin (A) is best suited for semiconductor encapsulation because it has good flow, a low coefficient of linear expansion, a high Tg, minimal moisture absorption, and crack resistance upon lead-free soldering.

    摘要: A device is provided for measuring an angle between two intersecting surfaces of a work. The device includes a light emitting device for inducing a light pattern on the surfaces of the work, a camera for picking up the pattern, and an image processor for processing the picture of the pattern and obtaining the angle of the work.
