. The second part of this is whether or not the solder is a tin/lead or a lead-free material. If it is lead-free then the time to reflow will be longer still as the melting temperature of the solder is higher, so it will take more time to reach those temperature

. In the reflow section, the peak soldering temperature varies depending on the solder paste used. Generally, the melting point temperature of the solder paste plus 20-40°C is recommended

; because none of them are exact drop-in replacements for tin/lead solder, all require some process adjustments. The primary difference between most of the new formulations and traditional solder is a higher melting point

window is 195-240 degrees. Because of the change of melting point of lead-free solder paste , lead-free soldering has brought great changes for soldering process
