Package Dimensions
The PCB layout footprint for the SE2568U is provided in
Figure 4. Typical case markings are shown in Figure 5. Package
dimensions for the 8-pin QFN are shown in Figure 6, and carrier
tape dimensions are provided in Figure 7.
Package and Handling Information
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 SE2568U is rated to Moisture Sensitivity Level 1 (MSL1) at
260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
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:
Skyworks Application Note: QFN Solder Reflow and Rework
Information Application Note, Document Number QAD-00045.
Skyworks Application Note: 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.
