Package and Handling Information Because of its sensitivity to moisture absorption, instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SE2611T is rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. It is capable of withstanding a Pb-free solder reflow. For additional information, refer to the Skyworks Application Note, Solder Reflow Information, document number 200164. dBm 8 20 dBm 500 ns 10 dB 7 dB 20 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 by Skyworks, please refer to the following Skyworks Application Notes: 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. Production quantities of this product are shipped in a standard tape and reel format.
