Unacceptable examples
The following are examples of unacceptable applications of the coating. Return new parts or
replace existing parts that exhibit similar applications.
Void I Void II Splash
Void I: The silver-colored coating shows missing areas of within the normal coated area.
Void II: The silver-colored coating shows missing areas along the edge of the coated area.
Splash: The silver-colored coating extends beyond the normal coated area.
Important: If you observe a heatsink or processor with a “splash” of special coating, rst try to
remove the excess by using the method described below under “Removing Stray Particles of
Coating.” If this approach does not remove the splash, return the part to Apple.
Removing Stray Particles of Coating
In rare cases, small particles or beads of the silver-colored coating may appear outside the normal
coated area of a replacement heatsink or processor. You must remove these particles before
installing the part. Failure to do so could result in damage to the part or the logic board.
