摘要:
An aromatic polycarbodiimide having structural units represented by formula (I) (wherein R represents a C3+ organic group and n is an integer of 2 to 300); a solution of the aromatic polycarbodiimide; a polycarbodiimide sheet; and an insulated electric wire. The polycarbodiimide has high solubility in organic solvents, has satisfactory processability, and is excellent in heat resistance and moisture resistance. The insulated wire has excellent durability under high-tension high humidity conditions and is highly reliable.
摘要:
A semiconductor sealing epoxy resin containing an epoxy resin, a phenol resin, a curing accelerator and an inorganic filler, which has the following properties, (X) to (Z): (X) 50 to 500 poise in terms of a viscosity at 175 °C, as measured using a flow tester, (Y) 1 x 105 poise or less in terms of the minimum melt viscosity, in a temperature distribution of viscosity, as measured at a shear rate of 5 (1/s) by means of a dynamic viscoelasticity measuring apparatus, and (Z) 2.0 or more in terms of a viscosity ratio (Z1/Z2) of a viscosity at 90 °C (Z1) to a viscosity at 110 °C (Z2), as measured at a shear rate of 5 (1/s) by means of a dynamic viscoelasticity-measuring apparatus. The semiconductor sealing epoxy resin is free from the occurrence of shift of the position of a semiconductor element by flow of a resin during sealing and of tilt of a chip by metal wire run or the like, and can be used for providing a semiconductor device exhibiting high reliability.
