Recommended reflow conditions Maximum temperature : 250ûC max. Rotary Potentiometers Slide Potentiometers 200ûC Temperature Preheat temperature : 150ûC. Room temperature 3s max. 2 min. max. 40s max. 4 min. max. Metal Shaft Insulated Shaft Knob Operating 2. Cleaning 3. Type of solder to be used 4. Soldering Cleaning should not be attempted. Use cream solder that contains 10 - 15 %wt flux. Mounting plate should also be soldered. Notes 1. When using an infrared reflow oven, solder may sometimes not be applied. Be sure to use a hot air reflow 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 250˚C or greater. 3. Conditions vary to some extent depending on the type of reflow bath used. Be sure to give due consideration to this prior to use. 398
