Pre-heating

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.

2. Soldering conditions differ depending on reflow soldering machines. You are requested to verify the soldering

conditions thoroughly beforehand.
