Soldering time

Soldering process time can be saved by preheating effect of N2 system. Look at the following graphs showing the soldering time difference with / without nitrogen gas in case of HAKKO FX-951 and HAKKO FX-838.

FX-951

Thermally-controlled high-power compact type (Digital) as a standard soldering iron for any soldering situation

FX-838

High power 150W soldering station suitable for soldering from large to fine components (Digital)for components requiring a large amount of heat

HAKKO FX-951
Test method: Measure the time until the workpiece reached to 250℃ at 5-points; setting temperature is 320℃ with nitrogen gas and 340 ℃ without nitrogen gas.:
Board Paper phenol copper, single-sided
Component Connector
Tip shape T12-D24 without nitrogen gas
T13-D24 with nitrogen gas
Setting temperature 340℃ without nitrogen gas
320℃ with nitrogen gas
Solder Lead-free solder (Sn-3Ag-0.5Cu) ø0.5



*Please refer to above values, which vary depending on soldering condition.

HAKKO FX-838
Test method: Measure the time until the workpiece reached to 250℃ at 5-points; setting temperature is 320℃ with nitrogen gas and 340ºC without nitrogen gas.
Board Paper phenol copper, single-sided
Component Connector
Tip shape T20-D24 with / without nitrogen gas
Setting temperature 340℃ without nitrogen gas
320℃ with nitrogen gas
Solder Lead-free solder (Sn-3Ag-0.5Cu) ø0.5

Comment Soldering time with nitrogen gas can be saved by preheating effect as the above test results. Preheating the workpiece enhances the solder flow so that the solderbility will improve.
