Influence of the high-melting-point solder addition on the thermo-mechanical reliability of solderable anisotropic polymer composites containing low- melting-point solder

The study demonstrates that incorporating high-melting-point solder into low-melting-point solder-based anisotropic polymer composites significantly enhances their thermo-mechanical reliability during thermal shock testing by strengthening initial bonding, suppressing microstructural coarsening, and slowing intermetallic compound growth.
