Parameter
Value
Peak temperature (RoHS compliant process)
245°C
Average ramp up rate to peak (217°C to Peak)
C / second max.
Preheat temperature
min=150°C; max=200°C
Ramp up time from min. to max. preheat temperature
60 … 120 seconds
Temperature maintained above 217°C
60 … 150 seconds
Time within 5°C of actual peak temperature

As results of soldering may vary among different soldering systems and types of
solder and depend on additional factors like density and types of components on
board, the values above should be considered as a starting point for further optimi-
zation.
