1.When using an infrared reow oven, solder may sometimes not be applied. Be sure to use a hot air reow oven or a
type that uses infrared rays in combination with hot air.
2.The temperatures given above are the maximum temperatures at the terminals of the potentiometer when
employing a hot air reow method. The temperature of the PC board and the surface temperature of the
potentiometer may vary greatly depending on the PC board material, its size and thickness. Ensure that the surface
temperature of the potentiometer does not rise to 250C or greater.
3.Conditions vary to some extent depending on the type of reow bath used. Be sure to give due consideration to this
prior to use.
