Mechanical Behaviour of Sn-Pb and Sn-Ag Soldering Alloys for Printed Circuit Boards of the Automotive Industry 2001-01-3220

In the present work, a comparative study of the constitutive equations describing the flow behaviour at relatively high homologous temperatures of eutectic tin-lead and tin-silver alloys is carried out. For this purpose uniaxial compression tests were performed on the latter two alloys at diverse strain rates and temperatures. Results showed that at relatively low temperatures the deformation response can be considered to be controlled by the same mechanism. However, the tin-lead eutectic, displayed superplastic behaviour at high temperatures.
