Without extensive testing of the filter media we are putting
boards/devices through our DI water closed loop system and see no
movement of thermal grease (Wakefield 120-8).

Subject: [TN] Thermal Grease


Good morning all,

A quick question, I hope.  Does anyone have experiences they want to
share
regarding the cleaning of assemblies that contain thermal greases?  We
use
a Dow Corning DC340 thermal conductive grease to aid in heat
transferrance.
There is currently a debate ongoing (culminating with a Friday meeting)
as
to the advisability of exposing such material to our Aquanox SSA
cleaning
regimen.

Part of me is concerned about the SSA attacking the silicone and
redistributing it everywhere.  But, one of the manufacturing centers has
indicated that they have been putting this grease through this cleaning
process for several years with no apparent problems.

Any thoughts on the matter?
