Package Information
2.0 Package Information
The component utilizes a 35 mm x 35 mm, micro FCPGA package (see Figure 2 through 
Figure 8). The data is provided for reference only. Refer to the device’s most recent 
datasheet for up-to-date data. In the event of conflict, the device’s datasheet 
supersedes data shown.
The processor connects to the baseboard through a 479-pin surface mount, zero 
insertion force (ZIF) socket. A description of the socket can be found in the Intel
®
Mobile Processor Micro-FCPGA Socket (mPGA479M) Design Guidelines.
The processor package has mechanical load limits that are specified in the processor 
datasheet. These load limits should not be exceeded during heatsink installation, 
removal, mechanical stress testing, or standard shipping conditions. The heatsink mass 
can also add additional dynamic compressive load to the package during a mechanical 
shock event. Amplification factors due to the impact force during shock must be taken 
into account in dynamic load calculations. The total combination of dynamic and static 
compressive load should not then exceed the processor datasheet compressive 
dynamic load specification during a vertical shock. It is not recommended to use any 
portion of the processor substrate as a mechanical reference or load bearing surface in 
either static or dynamic compressive load conditions.
