Heating method Double heating method with infrared heater. 2. Temperature measurement Thermocouple 0.1 to 0.2 ? CA (K) or CC (T) at soldering portion (copper foil surface). A heat resisting tape should be used for fixed measurement. 3. Temperature profile A B C D E F G H No. of reflows 250? 200? 150? 150? 2 min. 3s 40s 4 min. 2 time max. 1. When using an infrared refl ow oven, solder may sometimes not be applied. Be sure to use a hot air refl ow 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 reflow 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 refl ow bath used. Be sure to give due consideration to this prior to use. Notes are common to this series/models. 1. This site catalog shows only outline specifications.
