| Abstract: | The conductive adhesives composed by selecting epoxy resin system,Ag powder as main conductive filler with addition different masses of low melting point eutectic SnBi alloy were fabricated and its conductive and mechanical properties were investigated by the four point probe method and the universal material testing machine.It is found that when w(SnBi) keeps at 15%,the bulk resistivity and the shear strength of the adhesive reach 3.4×10-4 Ω·cm and 12.56 MPa,respectively.The addition of SnBi alloy not only improves the conductivity,but also increases the mechanical property of the connection. |
