标题: Lead-Free Solder Properties


International annealed copper standard: % of IACS=0.017241/ρ*100%
Notes:
1. 1MPa=145psi   1psi=6.895kPa  1kPa=0.0102 kgf/cm²  1psi=0.0703 kg f/cm²
2. Electrical conductivity and resistance:Electrical conductivity(%IACS)=0.017241/ρ*100%.
    Electrical conductivity and conductance: Electrical conductivity(%IACS)=σ/58.0*100%.
    58MS/m=100%IACS;  1%IACS=0.58MS/m;  1MS/m=1.7241%IACS
3. “-” represents no data available
4. 1W/(m·K) =1W/(m·℃)
5. Data with light blue color is only for reference
6 *27 represents the temperature of 20℃. The shear strength is 27MPa if the elongation rate is 0.1mm/min. In most cases, the shear strength decreases with temperature.
