11.2 Moisture Sensitivity and Storage
The ET1200 is shipped in a sealed moisture barrier bag (dry- pack). There is a “caution” label on the
dry-pack which contains all necessary information required for handling the devices. Refer to the
JEDEC standards J-STD-020 and J-STD-033 for more details (
http://www.jedec.org ).
The information on the dry-pack takes precedence over information in this chapter.
The moisture sensitivity level of the ET1200 is MSL 3. The maximum shelf-life of the ET1200 packed
in a dry-pack is one year after bag seal date. If the ET1200 is stored longer than one year, drying
(baking) is required before soldering.
Drying and re-packaging can have negative effects on solderability and conducting surfaces. To
minimize issues, the following steps should be taken:

Visual inspection of the ET1200 devices

solderability tests with some samples of the ET1200

final test of the product using the ET1200 with focus on the ET1200 connections
