Lay the heat sink down on your work table as shown below with the two 4-40 flat head screws in the holes
as shown. The screw size is not important. They are there only to help you align the thermal pad over the bare
metal area. (The figure shows two 3/8” {9.5mm} screws.)
Heat Sink Ready for Thermal Pad.
Locate the thermal pad and carefully separate the white protective coating from one side. There are three
layers: a clear plastic protective film, the thermal pad itself, and a white plastic protective film. The three layers
are shown in below. Remove only the white plastic protective film to expose the adhesive surface
underneath. A sharp knife is handy for separating the layers. Work carefully to avoid separating the clear
plastic protective film from the thermal pad. The thermal pad wrinkles easily if it is allowed to separate from
the clear plastic, and will not work properly unless it remains flat.
