Manual soldering is suggested
- Use soldering irons of which power is less than 30 Watt.
- Keep the temperature of soldering irons below 360 °C
- Only one soldering is allowed on each bonding pad.
- The maximum time from when a soldering iron comes into contact with the
parts that are to be connected until the joint is finished should not exceed
three seconds.
- Perform other procedures after the soldered pad cools down.
Suggested storage conditions: 25°C +/-10°C (77°F +/-50°F),
relative humidity 65% RH +/- 20% RH.
