Abstract

The development of Pb-free solders is very important in the electronic industries, as the restricting of the Pb in solders. Calculation phase diagram (CALPHAD) has been used to design the materials and study the technics of production. CALPHAD is the method for calculation of the phase equilibria based on the experimental data, thermodynamic models and the minimisation of Gibbs free energy. This paper introduced the principle of CALPHAD and its applications in Pb-free soldering, which include the designing of the solders, the prediction of the interface reaction, and the solidification of solders.
