Note:
The shipping tray cannot be heated above 65°C. If baking is required at the higher temperatures
displayed in in
, the modules must be removed from the shipping tray.
Any modules not manufactured before exceeding their floor life should be re-packaged with fresh desiccate and
a new humidity indicator card. Floor life for MSL (Moisture Sensitivity Level) 3 devices is 168 hours in ambient
environment
30°C/60%RH.

Laird surface mount modules are designed to be easily manufactured, including reflow soldering to a PCB.
Ultimately it is the responsibility of the customer to choose the appropriate solder paste and to ensure oven
temperatures during reflow meet the requirements of the solder paste. Laird surface mount modules conform
to J-STD-020D1 standards for reflow temperatures.
Important: During reflow, modules should not be above 260° and not for more than 30 seconds.
