Package and Handling Information
Because of its sensitivity to moisture absorption, this device
package is baked and vacuum-packed prior to shipment.
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 SKY77324 is capable of withstanding an MSL3/250 °C 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 attached in a reflow oven, the temperature ramp rate
should not exceed 5 °C per second; maximum temperature should
not exceed 250 °C. If the part is manually attached, precaution
should be taken to insure that the part is not subjected to
temperatures exceeding 250 °C for more than 10 seconds.
For details on attachment techniques, precautions, and handling
procedures recommended by Skyworks, please refer to Skyworks
Application Note: PCB Design and SMT Assembly/Rework,
Document Number 101752. Additional information on standard
SMT reflow profiles can also be found in the JEDEC Standard
J-STD-020.
Production quantities of this product are shipped in the standard
tape-and-reel format. For packaging details, refer to Skyworks
