Simply raising the temperature of a soldering iron because of the high melting point may result in faster oxidation and erosion. The problems with lead-free solder can be solved by using products which offer special characteristics described below.
It is these characteristics that HAKKO believes to be most important when using lead-free solder.
Accurate temperature control and excellent thermal recovery rate enable the use of lead-free solder without the need for setting a higher temperature.
We made iron tips compatible with lead-free solder by changing solder plating to tin plating.

For a flow solder bath, the special treatments given to the areas susceptible to erosion by solder can reduce the frequency of replacement of deteriorated parts.
For a static solder pot, we designed the pot, which deteriorates faster when using lead-free solder, so that it can be replaced more easily. This reduces the need for repair compared with conventional solder pot. The waiting time before operation can also be reduced by setting parameters according to solder types to make solder melting time shorter.
Conventional thermometers use a sensor which plates eutectic solder in a measuring point to allow thermal conductivity. Changing the solder on the measuring point into tin plating can prevent unnecessary soldering ingredients from adhering to the iron tip.
Wire-type cleaners help cause less tip oxidation during tip cleaning.
Wire-type cleaners also help cause less tip oxidation after tip cleaning by leaving a slight amount of solder that protects a tip surface from the air.
FT-710 or FT-720 not only help reducing the tip oxidation after tip cleaning, but also prevents the solder from scattering.
The wettability* of an iron tip can be recovered by removing oxides adhered to the tip with a rotating brush. This allows the tip to be used again.

"Wetness" is the phenomenon that a liquid which makes contact with a solid flows and spreads out. "Wettability" is the property of a metal surface which expresses the spreadability.
New heater structure improves thermal recovery rate, reduces temperature drop during work, and improves workability of lead-free solder. Moreover, the shorter distance between the nozzle and filter pipe reduces the chance of clogging with solder.
Applying hot air uniformly to a target eliminates temperature variation in the target, enabling efficient rework.
