Handling and Storage
ESD (Electrostatic Discharge)
Electrostatic discharge occurs naturally in the environ-
ment. With the increase in voltage potential, the outlet
of neutralization or discharge will be sought. If the ac-
quired 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.
MSL (Moisture Sensitivity Level)
Plastic encapsulated surface mount package is
sensitive to damage induced by absorbed moisture and
temperature.
Avago Technologies follows JEDEC Standard J-STD 020B.
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 below
which corresponds to a MSL classification level 6 to 1
according to the JEDEC standard IPC/JEDEC J-STD-020B
and J-STD-033.
WS1103 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-baked. MSL classification reflow temperature
for the WS1103 is targeted at 260°C +0/-5°C. Figure
19 and Table 7 show typical SMT profile for maximum
temperature of 260 +0/-5°C.
