1. The condition mentioned above is the temperature on the mounting surface of a PC board. There are cases where
the PC board's temperature greatly differs from that of the switch, depending on the PC board's material, size,
thickness, etc. The above-stated conditions shall also apply to switch surface temperatures.
（Except a part of Variety SKRM, SKRR Series）
2. Soldering conditions differ depending on reflow soldering machines. You are requested to verify the soldering
conditions thoroughly beforehand.
3. Ask us for the specifications of lead-free products.
Notes
1. Consult with us for TACT switch washing conditions.
2. Prevent flux penetration from the top side of the TACT switch.
3. Switch terminals and a PC board should not be coated with flux prior to soldering.
4. The second soldering should be done after the switch returns to normal temperature.
5. Use the flux with a specific gravity of at least 0.83.
