The bonding strength was approximately doubled by electroless Pd-P plating. Brittle Sn-Te intermetallic compounds were formed on the bonding interface of the thermoelectric elements without electroless Pd-P plating, and the fracture of the bond originated from these intermetallic compounds. A Pd-Sn solder reaction layer with a thickness of approximately 20 µm was formed under the Pd-P plating layer in the case of the electroless Pd-P plating, and prevented the diffusion of Bi and Te. In addition, the fracture did not occur on the bonding interface but in the thermoelectric elements for the electroless Pd-P plating because the bonding strength of the Pd-Sn reaction layer was higher than the shear strength of the thermoelectric elements.}, type={Artykuły / Articles}, title={Effect of Pd-P Layer on the Bonding Strength of Bi-Te Thermoelectric Elements}, URL={http://www.czasopisma.pan.pl/Content/113009/PDF/AMM-2019-3-28-Son.pdf}, doi={10.24425/amm.2019.129481}, keywords={Bismuth-Telluride, Thermoelectric module, Electroless Pd-P plating, Bonding strength}, }
