Essential technological requirement: The SMT reflow usually uses the air or the nitrogen carries on the forced convection heating as the craft gas, typical leadfree craft curve including four stages: Preheating, heat preservation, backflow and cooling. Must obtain the precise temperature curve, various heating zones temperature establishment, the transfer speed, cooling speed even ventilator speed must consider fully. The non-lead welding craft faces now the only question is: The backflow temperature is higher, the backflow temperature and the part may withstand the maximum temperature difference is smaller, causes the craft window compared to eutectic to weld the craft reduction.
