HANDLING AND PRECAUTIONS
• Before soldering, be sure to preheat components.
The preheating temperature should be set so that the
temperature difference between the solder temperature and
product temperature does not exceed 150°C.
• When hand soldering, apply the soldering iron to the printed
circuit board only. Temperature of the iron tip should not exceed
350°C. Soldering time should not exceed 3 seconds.
