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. 2. Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is highly recommended.
