Why Thermal Paste

If we don’t use thermal paste, the metal of the heat sink and the metal on top of the microprocessor (which is really the opposite side of the substrate of the chip) will meet metal to bare metal. When metals are machined and stamped they are not perfectly smooth and flat but more probably represent a very fine set of parallel hills and valleys from the machining process and stamped surfaces have a gentle roll of a fraction of thousandths of an inch. In practice the meeting of these hills and valleys makes an extremely small contact area - mostly air fills the gaps in the valleys.

As a result the conduction metal to metal is sparse and mostly air gap - and air is a bad conductor.

Covering the surfaces with a thin layer of thermal compound ensures that the air is displaced and the heat will flow through thermal compound much better than through air. Even though thermal compound is not as good a conductor as metal to metal the large area involved makes most of the heat go through a thin layer of thermal compound,

The difference it makes in then thermal path from the chip die to the substrate plate to the heat sink can make a significant difference in thermal resistance and lower the chip temperature by 10–20 degrees even while the surface of the heat sink appears to be no hotter than without the grease.

What are the most important properties thermal paste must have?

Highest thermal Conductivity: Thermal paste must have excellent thermal conductivity at ambient temperature, higher the thermal conductivity higher the heat flow, higher the life of equipment. Thermal paste plays important role in performance of the system. Thermal paste must take out the entire heat generated in the system very effectively  

High Temperature Resistance: Thermal paste should have excellent temperature resistance. Thermal paste should not melt in the system; it should not initiate the self heating

Consistency: Thermal Paste must have higher & constant consistency. Due to variations in system temperatures thermal paste must not lose its viscosity, viscosity of thermal paste must be same over wide temperature ranges. 

Non Drying: Thermal paste must not be dried till the life of the equipment or instrument

Chemical Nature: Thermal must be non hygroscopic in nature, if thermal paste by chemical nature attracts moisture it will damage the electrical as well as thermal properties.

Static Current: Thermal paste should not generate static current

Bleed: Thermal paste must have very minimum bleed for maximum system temperatures

Oxidation Resistance: Thermal Paste must have highest oxidation resistance so it will remain intact till more than expected life.

Reactivity: Thermal paste should not be reactive with metals, non metals.

Nimble Thermal Paste

We had designed specialty thermal paste for various applications. Our thermals paste are designed considering the needs of application based on amount of heat generated in the system , thermodynamics , thermal equilibrium,  rate of heat transfer, thermal conductivity , temperature in the system. Thermal grease designed & manufactured by us are used by various electronic equipments manufacturers for different applications. Apart from application requirements while designing thermal grease we had consider & put on the priority EHS parameters. Our thermal grease is safe to use whether it’s indoors or out door applications. Our thermal grease is safe to use and can be used without gloves, even in long term use its non harmful to human skin. Thermal grease manufactured by us is absolute free from VOC

Nimble thermal grease is so safe that it can be used in closed or air conditioned rooms . Thermal grease manufactured by us is free from ozone depleting compounds. Our all thermal greases are safe to the environment.  Thermal grease manufactured by us has excellent resistance to oxidation. Nimble Thermal grease can with stand high temperatures. Drop point of Nimble thermal greases are very high which ensures our customers for maximum safe limits within design parameters. According customer & applications requirement we had designed thermal grease with varying viscosities. Some applications needs thermal grease with lower viscosities so it can be applied by screen printing. We have thermal grease with higher viscosities in the range of 800 – 1000 Poise.

Our thermal paste never becomes brittle irrespective of its application method & thickness. Our thermal paste offer excellent heat dissipation irrespective of the quantum of heat generated.  Our thermal pastes are designed to offer excellent thermal resistance. All thermal paste designed by us offer long term resistance to thermal degradation which ensures maximum service life
