WebReflow Dynamics- Intermetallics. The goal of the soldering process is to form an intermetallic layer between the solder and the circuit board and the solder and the component. Simply explained, an intermetallic is a combination of the base metals with the solder that provides the mechanical and electrical integrity of the solder joint. WebA reflow process with a peak temperature of only 234°C and 60 seconds above 217°C is considered the low end of the window for SAC305. Despite SnCuNi’s higher melting point, it formed good joints, passing every standard test to which it was subjected. It demonstrated full compatibility with the cool range of the SAC305 window, establishing ...

It is found from EDX results that with the increasing of the number of reflow cycles, the layered IMC (No. 1) at the solder/pad interface tend to dissolve and entrap more base metal atoms (i.e., Cu).
WebStatistical analyses are conducted to compare the difference in IMC thickness growth between SAC305 solder joints and SnPb solder joints, and the difference in IMC thickness growth between after thermal shock and after thermal aging. Findings – The IMC thickness increases with higher reflow peak temperature and longer time above liquidus.
