PRECAUTIONS FOR USE Before soldering, be sure to preheat components. The 'T preheating temperature must be 150°C max. with attention paid to thermal shock. Natural cooling of components in the air is recommended. On the other hand, when dipping them in a solvent for purposes, such as cleaning, make sure that the temperature difference ('T) is 100° When performing hand soldering for circuit modification, apply the soldering iron to the copper foil area of the printed circuit board for 3 seconds or less. The temperature of the iron tip should not exceed 300°C. Use a wrist band to discharge static electricity in your body through the grounding wire. When incorporating the printed circuit board on which this prod-
uct is mounted into a frame, etc., do not apply stress to the product through local bending of the board by tightening of screws, etc.
Temperature(˚C) 150˚C max.
0 Preheating Make as short as possilble (within three seconds)
