SHENMAO America, Inc. is proud to introduce its latest innovation in response to the rising demand for ultra-thin electronic packages. As package thinness increases, issues like package warpage and its detrimental effects on production yield have become critical challenges. SHENMAO is addressing these concerns with its new Low-Temperature Solder (LTS) materials, which are engineered to lower reflow temperatures, mitigating PCB and substrate deformation while enhancing overall yield rates.

The electronics industry has mainly adopted the higher melting point Sn3Ag0.5Cu solder alloys for lead-free reflow soldering applications. For applications where temperature sensitive components and boards are used this has created a need to develop low melting point lead-free alloy solder pastes. Tin-bismuth and tin-bismuth-silver containing alloys were used to address the temperature issue with development done on Sn58Bi, Sn57.6Bi0.4Ag, Sn57Bi1Ag lead-free solder alloy pastes. Investigations included paste printing studies, reflow and wetting analysis on different substrates and board surface finishes and head-in-pillow paste performance in addition to paste-in-hole reflow tests. Voiding was also investigated on tin-bismuth and tin-bismuth-silver versus Sn3Ag0.5Cu soldered QFN/MLF/BTC components. Mechanical bond strength testing was also done comparing Sn58Bi, Sn37Pb and Sn3Ag0.5Cu soldered components. The results of the work are reported.
