Intel® 3210 and 3200 Chipset Thermal/Mechanical Design Guide

2. This is the maximum force that can be applied by a heatsink retention clip. The clip 

must also provide the minimum specified load of 7.6 lbf on the package to ensure 
TIM performance assuming even distribution of the load.

3. These specifications are based on limited testing for design characterization. 

Loading limits are for the package only.

To ensure that the package static load limit is not exceeded, the designer should 
understand the post reflow package height shown in 

Figure 2-5

. The following figure 

shows the nominal post-reflow package height assumed for calculation of a heatsink 
clip preload of the reference design. Please refer to the package drawing in 

Figure 2-1

 

to perform a detailed analysis.
