The preferred method is to shave from the edge to the center of the IHS. Note: The adhesive shaving step should be performed while the adhesive is partially cured, but still soft. This will help to keep the adhesive surface flat and smooth with no pits or voids. If there are voids in the adhesive, refill the voids with adhesive and shave a second time. 34.

Figure 54. Removing Excess Adhesive from IHS
33.
Using a blade, carefully shave any adhesive that is above the IHS surface
(Figure 54). The preferred method is to shave from the edge to the center of the
IHS.
Note:
The adhesive shaving step should be performed while the adhesive is partially cured,
but still soft. This will help to keep the adhesive surface flat and smooth with no pits
or voids.
If there are voids in the adhesive, refill the voids with adhesive and shave a
second time.
34.
Clean IHS surface with IPA and a wipe.
35.
Clean the LGA pads with IPA and a wipe.
36.
Replace the land side cover on the device.
37.
Perform a final continuity test.
38.
Wind the thermocouple wire into loops and secure or if provided by the vendor
back onto the plastic roll. (Figure 55).
