5. User Information
5.1 Soldering Recommendations
For DRY PACKED products,
T
EMIC recommends to strictly follow the procedure described
hereunder:
- Dry packed products must not be stored more than 1 year at 40°c - 90%rh
(worst storage conditions assumed)
- A longer storage period is allowed taking into account the following conditions:
5 years max at 25°c (+/-5°c) - 50%rh
- From opening of the packs, the product must be assembled within 48 hours.
(worst in-process storage condition assumed: 30°c - 60%rh)
- If they cannot be soldered within this time period, then the pieces must be dryed at
125°c for 24 hours. Only one drying is allowed.
- Max relative humidity allowed in the bag is 20% (readable on the indicator inside
the bag). If this value is reached, then the parts must be dryed at 125°C for
24 hours before mounting.
- For high sensitive products, the delay between pack opening and assembly is
reduced to 6 hours (Level 6 of JEDEC 22-A112). In this case, a warning printed on
each pack advises the user of this restriction .
5.2 DRY PACK Ordering rules
T
EMIC qualification procedure allows to classify products according to JEDEC 22-A112 and to
determine the convenient conditioning for safe customer use.
Nevertheless, even if the product is not classified as moisture sensitive, it is possible (for example if
storage conditions are not properly controlled) to order product with a Dry Pack.
In this case the product name suffix will be ":D" or ":xD".
5.3 ESD caution
The user must protect components against EOS and ESD damages by grounding personal and
workstations.
