The SE2574L 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: “QFN solder reflow and rework information application note”, Document Number QAD-00045 “Handling, packing, shipping and use of moisture sensitive QFN application note”, Document Number QAD-00044 Caution!
