摘要:
The present invention relates to an encapsulated epoxy-resin molding compound, comprising an epoxy resin (A), a hardening agent (B), and magnesium hydroxide (C), wherein the magnesium hydroxide (C) has a [101]/[001] peak intensity ratio of 0.9 or more as determined by X-ray diffraction, a BET specific surface area of 1 to 4 m2/g, and an average particle diameter of 5 μm or less, and provides an encapsulated epoxy-resin molding compound superior in flame resistance moldability and also in reliability such as reflow resistance, moisture resistance, high-temperature storage stability, and thus, favorable for sealing VLSI, and an electronic component device carrying an element sealed with the molding compound.

The present invention relates to an encapsulated epoxy-resin molding compound, comprising an epoxy resin (A), a hardening agent (B), and magnesium hydroxide (C), wherein the magnesium hydroxide (C) contains magnesium hydroxide coated with silica, and provides a non-halogenated and non-antimony encapsulated epoxy-resin molding compound superior in flame resistance moldability and also in reliability such as reflow resistance, moisture resistance, high-temperature storage stability, and thus, favorable for sealing VLSI, and an electronic component device carrying an element sealed with the molding compound.
摘要:
The present invention relates to an encapsulated epoxy resin composition containing an epoxy resin (A), a hardening agent (B), and magnesium hydroxide (C), the magnesium hydroxide (C) comprising magnesium hydroxide particles with its crystal appearance in a hexagonal column shape having two hexagonal top and bottom base faces in parallel with each other and six peripheral prism faces formed between the base faces and having a length in the c-axis direction of 1.5×10−6 to 6.0×10−6 m, and provides an encapsulated epoxy resin composition favorable as a sealer for VLSI's that is superior in flame resistance and also in reliability such as moldability, reflow resistance, moisture resistance and high temperature storage characteristics and an electronic component device containing an element sealed with the composition.
