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!
