1. Prevent flux penetration from the top side of the TACT SwitchTM.
2. Switch terminals and a PC board should not be coated with flux prior to soldering.
3. The second soldering should be done after the switch is stable with normal temperature.
4. Use the flux with a specific gravity of min 0.81.
（EC-19S-8 by TAMURA CORPORATION, or equivalents.）
Notes
1. Please confirm the specifications of our product for the detailed condition.
2. Soldering conditions differ depending on reflow soldering machines.
Prior verification of soldering condition is highly recommended.
