2.1 Package Mechanical Specifications
The processor is packaged in a Flip-Chip Land Grid Array package that interfaces with
the motherboard via the LGA1156 socket. The package consists of a processor
mounted on a substrate land-carrier. An integrated heat spreader (IHS) is attached to
the package substrate and core and serves as the mating surface for processor thermal
solutions, such as a heatsink.
Figure 2-1 shows a sketch of the processor package
components and how they are assembled together. Refer to Chapter 3 and Chapter 4
for complete details on the LGA1156 socket.
The package components shown in Figure 2-1 include the following:
1. Integrated Heat Spreader (IHS)
2. Thermal Interface Material (TIM)
3. Processor core (die)
4. Package substrate
5. Capacitors
Note:
1. Socket and motherboard are included for reference and are not part of processor package.
2. For clarity the ILM is not shown.
