– ET1100 Hardware Description
11.3 Moisture Sensitivity and Storage
The ET1100 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
The information on the dry-pack takes precedence over information in this chapter.
The moisture sensitivity level of the ET1100 is MSL 3. The maximum shelf-life of the ET1100 packed
in a dry-pack is one year after bag seal date. If the ET1100 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 ET1100 devices
solderability tests with some samples of the ET1100
final test of the product using the ET1100 with focus on the ET1100 connections
