Abstract:
1. A method for manufacturing an electronic component, comprising: forming a piezoelectric device on a surface of a substrate, said piezoelectric device including a vibration unit, a first electrode electrically connected to said vibration unit, and a first metal layer provided on said surface so as to annularly surround at least said vibration unit; forming a printed circuit substrate provided with a second electrode; fixing a conductive bump to one of said first electrode and said second electrode; providing solder material, with a solidus temperature lower than a solidus temperature of said bump, as an annular layer on one of: aligning said piezoelectric device and said printed circuit substrate in an aligned state such that: heating said bump to a temperature lower than the solidus temperature of said solder material so as not to melt said solder material, and press-bonding said bump to said another one of said first electrode and said second electrode; and heating, melting and expanding said solder material at a temperature lower than the solidus temperature of the bump, after said heating and said press-bonding is completed and with said piezoelectric device and said printed circuit board in said aligned state and stationary relative one another, so as to fill said annular gap with said solder material thereby forming a sealing member connecting said first metal layer with said printed circuit substrate via the solder material, and sealing a space between said printed circuit substrate and first metal layer.
