There are cases where the P board's temperature greatly differs from that of the switch, depending on the P board's material, size, thickness, etc. The above-stated conditions shall also apply to switch surface temperatures.. Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is highly recommended.
