SOLDERING RECOMMENDATIONS

See Application notes

CAUTION

Reflow soldering must be done within 72 h while stored

under a max. temperature of 30 °C, 60 % RH after opening

the dry pack envelope.

RECOMMENDED METHOD OF STORAGE

Dry box storage is recommended as soon as the hermetic

bag has been opened to prevent moisture absorption. The

following conditions should be observed, if dry boxes are not

available:

• Storage temperature 10 °C to 30 °C

• Storage humidity ≤ 60 % RH max.

After more than 72 h under these conditions, moisture

content will be too high for reflow soldering.

In case of moisture absorption, the devices will recover to the

former condition by drying under the following condition:

192 h at 40 °C + 5 °C/- 0 °C and < 5 % RH (dry air/nitrogen) or

96 h at 60 °C + 5 °C and < 5 % RH for all device containers

(not suitable for reel) or

24 h at 125 °C + 5 °C (not suitable for reel)
