Packaging - What packages have Moisture Sensitivity Level (MSL) numbers? The PD8 (and other Pin-Through-Hole packages) do not have MSL numbers, why not?

Description

What packages have Moisture Sensitivity Level (MSL) numbers? Also, why does the PD8 package not have an MSL classification?

Solution

Only SMT packages such as BGAs, QFPs, etc. are classified according to their MSL level.

 

Non-SMT packages such as the PD8 package do not get exposed to high reflow temperatures. 

because only the leads are heated during the soldering process, package delamination due to the reflow process is not a concern.

Moisture sensitivity levels (MSLs) for each package are also provided in the Device Package User Guide, available at:
