Reliability of Lead-Free (SACX) Solder Joints
<emphasis role="bold">Introduction</emphasis> The effect of a very low level of doping of Ce (cerium) on the SnAgCu solder is presented. Emphasis is placed on the determination of the material properties (such as the temperature and strainrate–dependent Young’s modulus, yield stress, ultimate strength, and the temperature- and time-dependent creep) and the intermetallic compounds (IMC) on organic solderability preservative (OSP) and NiAu (electroless Ni and immersion Au) copper surface finishes of the new Sn3wt%Ag0.5wt%Cu0.019wt%Ce (SACC) lead-free solder. The PCB (…
