Reflow peak
Webcomponent. Refer to Table2 for peak package reflow body temperature information. In any case, a reflow profile with the lowest peak temperature possible should be used. For backward-compatible assembly, a Pb-free reflow profile may be used. A minimum peak reflow temperature of 230°C is recommended to achieve complete mixing of SnPb paste … WebPeak Temperature – The maximum temperature experienced at any point on an assembly during reflow soldering.
