| 1. Soldering iron |
| 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.
|
|
| 2. Solder feeding |
| Splashes of solder and flux can be reduced by making a groove in solder.
|
|
| 3. Solder bath |
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. |
|
| 4. Thermometer |
| 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.
|
|
| 5. Cleaner |
| Wire type cleaners help less oxidation which is a common problem during cleaning. |
 |
Wire type cleaners help less oxidation after cleaning because they remove oxides and excessive solder while leaving some solder on the iron tip.
Sponge type cleaners completely remove solder from the iron tip, which is one of the causes of enhanced oxidation of a tip in lead-free soldering. Another disadvantage is that the temperature of the tip greatly decreases due to a sponge absorbing water.

|
|
| 6. Maintenance |
| 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.

What is wettability?
"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.
