HANDLING AND STORAGE
1. ESD (Electrostatic Discharge)
Electrostatic discharge occurs naturally in the environment. With the increase in voltage potential,
the outlet of neutralization or discharge will be sought. If the acquired discharge route is through a
semiconductor device, destructive damage will result.
ESD countermeasure methods should be developed and used to control potential ESD damage
during handling in a factory environment at each manufacturing site.
NOTE : Module products should be considered extremely ESD sensitive

2. MSL (Moisture Sensitivity Level)
Plastic encapsulated surface mount package is sensitive to damage induced by absorbed
moisture and temperature. WAVICS follows JEDEC Standard J-STD 020A. Each component
and package type is classified for moisture sensitivity by soaking a known dry package at various
temperatures and relative humidity, and times. After soak, the components are subjected to three
consecutive simulated reflows.
The out of bag exposure time maximum limits are determined by the classification test describe
above which corresponds to an MSL classification level 6 to 1 according to the JEDEC standard
IPC/JEDEC J-STD-020A and J-STD-033.
WS1111 is MSL3. Thus, according to the J-STD-033 p.11 the maximum Manufacturers
Exposure Time (MET) for this part is 168 hours. After this time period, the part would need to be
removed from the reel, de-taped and then re-bake.
Mandatory bake before use. After bake, must be reflowed within
the time limit specified on the label

3. Storage Conditions
Packages described in this document must be stored in sealed moisture barrier, anti-static bags.
Shelf life in a sealed moisture barrier bag is 12 months at <40
o
C and 90% relative humidity (RH)
J-STD-033 p.7.
3-1. Out-of-Bag Time Duration
After unpacking the device must be soldered to the PCB within 168 hours as listed in the
J-STD-020A p.11 with factory conditions <30
o
C and 60% RH.
3-2. Baking
It is not necessary to re-bake the part if both conditions( storage conditions and out-of-bag
condition ) have been satisfied. Baking must be done if at least one of the conditions above have
not been satisfied. The baking conditions are 125
o
C for 24 hours J-STD-033 p.8.
CAUTION: Tape and reel materials typically cannot be baked at the temperature described above.
If out-of-bag exposure time is exceeded, parts must be baked for a longer time at low
temperatures, or the parts must be re-reeled, de-taped, re-baked and then put back on tape and
reel. (See moisture sensitive warning label on each shipping bag for information of baking)
