Patent ID: 8079141

Claim:
A method for providing a solder connection, which electrically connects a first electronic component having a solder bump to a second electronic component having a protruded electrode, comprising: forming an adhesive agent layer in a surface that is the same with one surface of a surface for forming said solder bump provided in said first electronic component and a surface for forming said protruded electrode provided in said second electronic component; disposing said solder bump so as to face said protruded electrode to align said first electronic component with said second electronic component; and heating and compressing said solder bump and said protruded electrode while said solder bump and said protruded electrode in mutually facing arrangement are in contact with each other to cause a compressive deformation of said solder bump and said protruded electrode, wherein said adhesive agent layer is formed in said forming said adhesive agent layer so as to satisfy a relation of: A+B>C, where a height of said solder bump before the compressive deformation is presented as A [μm], a height of said protruded electrode before the compressive deformation is presented as B [μm], and a thickness of said adhesive agent layer is presented as C [μm], and wherein said solder bump and said protruded electrode are deformed in said heating and compressing said solder bump and said protruded electrode so as to satisfy a relation of: D+E is substantially equivalent to C, where a height of said solder bump after the compressive deformation is presented as D [μm], and a height of said protruded electrode after the compressive deformation is presented as E [μm].
