4.2.4.2 Processing Life
ELS81-US must be soldered to an application within 72 hours after opening the moisture bar-
rier bag (MBB) it was stored in.
As specified in the IPC/JEDEC J-STD-033 Standard, the manufacturing site processing the
modules should have ambient temperatures below 30°C and a relative humidity below 60%.
4.2.4.3 Baking
Baking conditions are specified on the moisture sensitivity label attached to each MBB (see
Figure 52 for details):
• It is
not necessary to bake ELS81-US, if the conditions specified in Section 4.2.4.1 and Sec-
tion 4.2.4.2 were not exceeded.
• It is
necessary to bake ELS81-US, if any condition specified in Section 4.2.4.1 and Section
4.2.4.2 was exceeded.
If baking is necessary, the modules must be put into trays that can be baked to at least 125°C.
Devices should not be baked in tape and reel carriers at any temperature.
4.2.4.4 Electrostatic Discharge
Electrostatic discharge (ESD) may lead to irreversable damage for the module. It is therefore
advisable to develop measures and methods to counter ESD and to use these to control the
electrostatic environment at manufacturing sites.
Please refer to Section 3.6 for further information on electrostatic discharge.
