Can Maxims standard reflow temperature range lead-free and leaded parts be mixed during board reflow? What reflow temperature would be used in this scenario?
Maxim’s lead-free termination parts can be mixed with leaded termination parts and reflowed at a lower temperature (240°C) with proper reflow conditions and compatible solder paste. However, the reliability of Maxim parts with leaded terminations are not guaranteed at higher reflow temperature (above 240°C). Some reference sources show data that define a reduction in solder joint reliability by as much as 33% less than Eutectic solder joints when lead and lead-free metallurgies are mixed.
