I think you can use a thomermal couple to verify the actual temperature.

Hot air temp 425 C is too high for the some components repair. You should check whether the component can bear such high temp, or not.


Thanks and best regards

[RMX:##] [TGAsia] measure the hot air temperature method





Hi,All:
In IPC 7721 and 7711 document just mentioned the hot air temperature  is approximately 425¡æ and adjust it if necessary £¬but it didn¡¯t define the test method to get the real  temperature.
Do you have the relative solutions?
Thanks,
