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 acquired

discharge route is through a semiconductor device, de-

structive 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 tempera-

ture.

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 con-

secutive simulated reflows.

The out of bag exposure time maximum limits are de-

termined 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.

ACPM-7381 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 ACPM-7381 is targeted at 260° +0/-5°C. Figure 17 and

Table 7 show typical SMT profile for maximum tempera-

ture of 260 +0/-5°C.
