se2521a80 SiGe Semiconductor, se2521a80 Datasheet - Page 10

• Manufacturer Part Number: se2521a80
• Description: 2.4 Ghz Wireless Lan Front End
• Manufacturer: SiGe Semiconductor

Package Information
Figure 7 shows the detailed device package diagram. The pads on the SiGe RF modules are plated with gold over
nickel, with a gold thickness of nominally 0.75 um. The modules can be reflowed onto FR4 based material using
eutectic SnPb or common tin based Pb free solder pastes.
Package Handling Information
Because of its sensitivity to moisture absorption, 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 SE2521A80 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 by SiGe, please refer to:
