- Clean the underside of the transistor
module with contact spray and a non-
linting cloth
- Place a blob of heat-transfer
compound on a flat, clean and smooth
surface (e.g. coated wooden board)
- Using an application roller, spread the
heat-transfer compound evenly across
the surface
- Roll alternately from left to right until
part of the surface is completely and
evenly covered with heat-transfer
compound
- Roll alternately at right angles to the
previous direction until part of the
surface is completely and evenly
covered with heat-transfer compound
- Once there is an even, thin layer of
compound on the roller of the
application tool, lift the tool out of the
compound
Note! If the heat-transfer
compound is not applied to the
component in a complete, gap-
free layer, this may result in heat-
transfer problems.
If too thick a layer of heat-transfer
compound is applied, this also impairs
heat transfer, and the transistor module
may break when the fixing screws are
tightened.
- Roll the compound approx. two or
three times, until the underside of the
transistor module is completely
covered
