Patent ID: 8023277

Claim:
An electronic component integrated module comprising: a wiring board; an electronic component provided on said wiring board; solder for electrically connecting said electronic component onto said wiring board; and an encapsulating resin provided on said wiring board for encapsulating said electronic component and said solder, wherein: an average linear thermal expansion coefficient α of said encapsulating resin calculated by the following Formula 1 is not less than 17×10 −6 /° C. and not more than 110×10 −6 /° C.: α={α1×( Tg−Tr )+α2×( Tp−Tg )}/( Tp−Tr ), where Formula 1 α1 indicates a linear thermal expansion coefficient of said encapsulating resin obtained at a temperature lower than a glass transition temperature thereof; α2 indicates a linear thermal expansion coefficient of said encapsulating resin obtained at a temperature exceeding the glass transition temperature; Tg indicates the glass transition temperature of said encapsulating resin; Tr indicates room temperature; and Tp indicates a peak temperature of packaging of said electronic component integrated module, and the Tg in the Formula 1 is 35° C. or more and 94° C. or less.
