Thermal conductive silicone piece: it’s based on silica gel material; add some metal oxide as the auciliary materials. It’s medium about heat conduction material by a special technology.
Silicone rubber puts organic ilicon resin as the cohere materials. Fill the thermal conductive powder; it is polymer composite that is a target of thermal conductivity.

There are some materials:
Organic silicon resin (basic material)
Insulating thermal conductive filler:Alox、Mgo、CBN、ALN、BeO、quartz and other Organic Slicon plasticizer: MgOH、 ATH
Inorganic colorant (color divisional)
Cross-linking agent (bond performance requirements)
Catalyst (technology nolding requirements)
Thermal conductive silicone piece only make an effect in heat conduction. Make a well conection with thermal conductive pathways, they will consist a heat sink model with cooling fin.

The advantage of thermal conductive silicone piece:
Thermal conductive silicone piece has more advantages than thermally conductive silicone
Heat conductivity codfficient’s range and staility
Insulating property
Suspension sound-absorbing effect
Install、test、usful again, and its convenience
Reduce heat sink and heat radiation structure’ requirements

How to use the thermal conductive silicone piece?
Put the thermal conductive silicone piece join in the project of the construction、hardware and circuit design in the early design.
Condideration factor: oefficient of thermal conductivity calculation, structural calculation, EMC calculation, suspension sound-asorbing calculation, install and testing and so on.
Select heat dissipation method, electronics products get smaller and smaller and very light. Usually it was heat dissipation, and it is passively. Traditionally, the main mothed is cooling fin. But the cooling fin is cancelled now. We all use heat dissipation structure or two of them combine. In different sisytem and environment, choose a best buys.

Select cooling fin mothed. You had better use metal hanger or pushpin, and thickness 0.5mm thermal conductive silicone piece. These motheds are very convenience and the effect is good than thermal conductive double-sided adhesive.
