摘要:
An epoxy resin composition which can be used as a semiconductor encapsulating resin and in which the improvement of flame retardancy can be attained by suitably adapting a crosslinked structure itself of a cured article without using any flame retardant material and without particularly highly filling an inorganic filler. The epoxy resin composition includes an epoxy resin (A), a phenolic resin (B), an inorganic filler (C) and a curing accelerator (D), wherein a flexural modulus E (kgf/mm2) at 240±20% C of a cured article obtained by curing the composition is a value satisfying 0.015 W+4.1≦E≦0.27 W+21.8 in the case of 30≦W

摘要:
A metal cap involved in a cavity down mounting package to be subjected to a seam welding with at least a roller electrode, wherein the metal cap has a square like external shape with four corners being so rounded that each corner has a radius of curvature in the range from 1/10 to 3/8 of a length on each side of the square like shaped metal cap thereby the seam welding is carried out by a combination of a straight movement of the roller electrode along straight sides of the metal cap and adjacent part of the rounded corners to the straight sides and a rotary movement of the roller electrode around a center axis of the metal cap and the roller electrode moves along the rounded corners except adjacent portions to the straight side of the metal cap.
