Similar mechanical properties with Sn 63 Pb 37, Sn 62 Pb 36 Ag 2 and Sn 60 Pb 40, suitable lead-free replacement. Contains eutectic Sn-In phase with melting point at 118 °C, avoid use above 100 °C. Sn 86.9 In 10 Ag 3.1: 204: 205 [48] Yes: Potential use in flip-chip assembly, no issues with tin-indium eutectic phase. In 97 Ag 3: 143 [49] Yes: Yes
Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder.It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [1] as it is near eutectic, with adequate thermal fatigue properties, strength, and wettability. [2]

Sn 60 Pb 40 is slightly cheaper and is often used instead for cost reasons, as the melting point difference is insignificant in practice. On slow cooling gives slightly brighter joints than Sn 60 Pb 40. [17] Yield strength 3,950 psi (27.2 MPa), tensile strength 4,442 psi (30.63 MPa). [18] Sn 91.0, Zn 9.0: 198 °C (388 °F) yes
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]
It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate tensile strength.
