TX2550 M4 Upgrade and Maintenance Manual 369
11.3.4 Applying the thermal paste to the CPU surface
I For Japan, the service engineer must follow the instruction provided
separately.
I If the CPU upgrade or replacement kit contains a new CPU heat sink, a
thin layer of thermal compound has already been pre-applied to its lower
surface. In this case, it isn’t necessary to apply thermal paste to the CPU
surface.
Figure 266: Thermal paste syringe
One thermal compound syringe (FTS-FSP:P304000004) contains thermal
paste for three CPUs.
In order to determine the correct amount of thermal paste (equal to 1.0 gram),
divide the grey area of the syringe up into three equal segments.
I Add graduation marks to the syringe using a permanent marker to help
you apply the thermal paste.
