Recommended method of storage
Reflow Terms: JEDEC Level 4 Specification
Dry box storage is recommended as soon as the aluminum bag has been opened prevent
1. Over-current-proof
Customer must apply resistors for protection, otherwise slight voltage shift might cause
big current happen. (Burned-out might happen).
2. Storage
(1) Do not open moisture proof bag before components are ready to use.
(2) Before opening moisture proof bag, components should be kept at 30 or less and
90%RH or less.
(3) Components should be used within a year.
(4) After opened moisture proof bag, components should be kept at 30 or less and
70%RH or less.
(5) Components should be used within 168 hours after opened moisture proof bag.
(6) If the moisture absorbent material (silica gel) has faded away or the components
have exceeded the storage time, baking treatment should be performed using the
following conditions. (Baking treatment: 60±5 for 24 hours)
ESD Precaution:
Proper storage and handing procedures should be followed to prevent ESD damage to
the devices especially when they are removed from the Anti-static bag. Electro-Static
Sensitive Devices warning labels are on the packing.

Recommended Solder Profile
Notice:
(1) Reflow soldering should not be done more than two times.
(2) When soldering, do not put stress on the devices during heating.
(3) After soldering, do not warp the circuit board.
Soldering Iron
Each terminal is to go to the tip of soldering iron temperature less than 350
for 3
seconds within once in less than the soldering iron capacity 25W. Leave two seconds and
more intervals, and do soldering of each terminal. Be careful because the damage of the
product is often started at the time of the hand solder.
Repairing
Repair should not be done after the device have been soldered. When repairing is
unavoidable, a double-head soldering iron should be used (as below figure). It should be
confirmed beforehand whether the characteristics of the device will or will not be
damaged by repairing.
