ELECTRONIC-COMPONENT-EQUIPPED SUBSTRATE AND METHOD FOR PRODUCING SAME

摘要

A method for producing an electronic-component-equipped substrate obtained by mounting an electronic component (14) onto one principal surface of a metal plate (10) comprising copper, or (in the case that a copper-plating film (20) is formed on the front surface thereof) aluminum or an aluminum alloy, wherein: a surface treatment causing surface roughness to be 0.4μm or higher is performed by roughening the one principal surface (or the surface having the copper-plating film (20)) (i.e. the surface to which the electronic component (14) is to be mounted) of the metal plate (10); a silver paste is applied to said principal surface (or the surface having the copper-plating film (20)), and the electronic component (14) is positioned thereon; thereafter, a silver bonding layer (12) is formed by sintering the silver in the silver paste; and the electronic component (14) is bonded to the one principal surface (or the surface having the copper-plating film (20)) of the metal plate (10) by the silver bonding layer (12).
