Package Handling Information
Because of its sensitivity to moisture absorption, instructions on the shipping container label must be followed
regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption
may occur when the part is subjected to high temperature during solder assembly. The SE2597L is capable of
withstanding a Pb free solder reflow. Care must be taken when attaching this product, whether it is done manually or
in a production solder reflow environment. If the part is manually attached, precaution should be taken to insure that
the device is not subjected to temperatures above its rated peak temperature for an extended period of time. For
details on both attachment techniques, precautions, and handling procedures recommended, please refer to:
 “Quad Flat No-Lead Module Solder Reflow & Rework Information”, Document Number QAD-00045
 “Handling, Packing, Shipping and Use of Moisture Sensitive QFN”, Document Number QAD-00044
 “ESD Control Policy”, Document Number SQ03-0062
Caution! Class 0 ESD sensitive device
