. These gold alloys have a lower constant of thermal expansion (CTE) of 15 ppm/C compared with indium (32 ppm/C) so thermal mismatch strains are smaller

. Since bulk of real-life solder joint failures are caused by the mismatch between the coefficients of thermal expansion between the component and the substrate, board level thermal cycling in air has
