Slave Controller – ET1200 Hardware Description III-57

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
