Low Silver Solder Alloys with Good Drop Shock and Thermal Cycle Reliability

SAC105 was shown to have better drop shock reliability than SAC305 however SAC105 thermal cycle performance was not necessarily as good at SAC305. Small quantities (0.1% or so) of some elements .. read more

A Compliant and Creep Resistant SAC-Al (Ni) Alloy

Addition of Al into SAC alloys reduces the number of hard Ag3Sn and Cu6Sn5 IMC particles,and forms larger,softer non-stoichiometric AlAg and AlCu particles. This results in a significant reduct .. read more

The Effect of Ni on the Microstructure and Behaviour of the Sn-Cu Eutectic Lead-free Solder

While the Ni-stabilized Sn-0.7Cu alloy is now well established as a viable lead-free solder in large scale commercial printed circuit board assembly the effect of Ni is not yet fully understood .. read more
