Is PCM Reworkable?

A: If the pahse change material has not gone through phase change, the material
will readily release from the device surface. For this situation, the
PCM material will not likely have to be replaced.
If the material has gone through the phase change, it will adhere
very well to both surfaces. In this case, GLPOLY suggests warming
the heat sink to soften the PCM compound for easier removal
from the processor. Replace with a new piece of PCM thermal pad
