37 tin silver phase diagram

The stability of the β‑tin phase down to temperatures of 13.2 °C is demonstrated in phase diagrams of common alloys of tin with varying concentrations of bismuth, lead, or silver [7,20]. According to the phase diagrams, the transformation from β‑tin to α‑tin will occur in the small corner of the β‑tin phase region for ... Shiny smooth silver color upon reflow for good cosmetic appearance; Melting point temperature increases after initial reflow, as gold is consumed from the gold plated mating surfaces to increase the gold content. This is an advantage and dis-advantage (refer to Figure 1: Gold-Tin Phase Diagram)

Tin/silver alloys were developed as an alternative to lead-containing solders. Typical commercial tin/silver alloys contain between 3 and 5% silver. Tin/Silver solders are used for high temperature, high reliability interconnect applications. Solder joints using Tin/Silver alloys maintain better high temperature strength then tin/lead solders. The silver (Ag)-platinum (Pt) phase diagram shown below introduces a few more concepts that the phase diagrams discussed previously did not contain. Similar to the eutectic system, there is a distinct phase on each side of the diagram relating to a high purity of each species. In this diagram, there is a phase that has a high concentration of ...

In this section, the Pb-Sn phase diagram will be discussed in detail, but first there a few basic components of phase diagrams to discuss. First there are the axes. The vertical axis shows temperature, while the horizontal axis shows the concentration of some species. In this phase diagram, the two species being considered are the elements lead and tin, and the horizontal axis refers to the amount of tin in the system.

Grey or α-tin has a diamond-like lattice and is non-metallic, stable below 13.2 °C. White or β-tin has a body-centred tetragonal lattice and is metallic - the form normally encountered. For this reason the polymorphism is commonly ignored in phase diagrams involving tin, for example in Fig. 1.3 the α-phase is β-Sn!
