Thermal interface mateiral introduction
Thermal Interface Materials are widely used for the heat conduction of IC and electronic products, which is to fill the small gap and rough holes between two material, to reduce the thermal resistance and improve the thermal conductive performance.
To keep the work temperature of the component junction within the safety temperature, the heat from the semiconductor must be transferred to the surroundings. The procedure include the heat transferred from the surface of device to the heatsink and the surroundings. The heat sink shuld be attached with the device carefully to make the thermal resistance as small as possible.If attach the heat sink with surface of the semiconductor, it require the two part should be contected tightly. The surfaces are always rough, which only can be seen under the microscope. When the two surfaces contected, only the high points are touched, the low points form the air gap. And there are over 90% of the contact zone are air gap, which means it will be the thermal resistance.The thermal interface materials can fill the air gap and the rough surface, its thermal conductivity is much higher that the air, through the TIMs, the thermal resistance of the junction will be less, and the temperature will be lower.
LE series thermal grease has good thermal conductive Performance and reliability, which is extremly suitable for the heat transfer of theCPU, GPU and other heating power components. As LE series has low adhesion, it can fully contact with the surface,which result in very low interface thermal resistance and high thermal conductivity.Plz apply the grease by the screen printing, the 60-80 Me SH nylon mesh and 70-80 hardness rubber scraper are recommended, leave 45 degrees between the scraper and the apply surface.
- between Semiconductor and heatsink
- between CPU and heatsink
- between power resistor and base
- thermoelectric cooler
- the surface of temperature regulator and assembly
- high-power LED lighting

Q:What’s the thermal conductivity test method given on the data sheet?
A: All the data in the sheet are tested out by the third party. ASTM D5470 is utilized to test the thermal conductivity.
Q: How to find a right thermal conductivity for your application?
A: It depends on the watts of power source, ability of heat dissipation. For any customers, please contact us for the technical support.
Q: Are thermal pads offered with tacky?
A: Yes, all the thermal pads have its inherent tacky. All the models are natural tacky for two sides, except for the LCP series ,only one side has natural tacky. LCB series thermal pads can be cover 3M glue with strong
Q: Are thermal pads reworkable?
A: It’s depend on the application and the pad being used. Thermal pads have been reused before, however,it’s up to the judgment of product designer, to see whether the pads could withstand reuse.
Q:Will the heat make the thermal pads softer?
A: ShoreC 20~80 ,there is no significant change in the hardness of thermal pads, as gap filler.
Q: What’s the tolerance for the thickness?
A :Normally ±0.1mm.
Q: Are the thermal pads electrical insulating?
A: Yes, all thermal pads are electrically isolated.
Q: What’s the shelf life for thermal pads?
A: Shelf life for thermal pad is one year after the date of manufacture. For the pads with adhesive, the shelf life is 6months after the date of manufacture. After these dates, all the characters should be retested.
Q: Can the thermal pads be with fiberglass?
A: YES, we could have thermal pads with fiberglass center to improve customer specific requirements for the tensile strength.LCP series has fiberglass on its surface, all other models will be made at your requirement.
