Q: Why use the thermal interface material (TIM)?
A: The use of a thermally conductive material eliminates the air gap between the two contact surfaces by the integration of the rough and uneven mating surfaces. Since the thermal conductivity of the material is much greater than the air it will replace, the resistance through the joint is reduced and the temperature at the junction of the device will also decrease.
Q: What are the common thermal interface materials (TIM)?
A: At present, the common thermal interface materials include synthetic graphite sheets, natural graphite sheet, thermal silicone sheets, Vc uniform temperature plate, thermal gels, thermal grease, thermal paste graphene sheets, and thermal insulation sheet.
Q: What is graphene?
A: Graphene is a two-dimensional carbon nanomaterial composed of a carbon atom and a sp2 hybrid orbital to form a hexagonal honeycomb lattice. It has the highest thermal conductivity which is 10 times as copper. The highest strength, harder than diamonds; the largest specific surface area, 4 grams can be covered with a football field.
Q: What are the advantages of graphene reinforced thermal conductive materials and traditional thermal conductive materials?
A: Compared with the traditional thermal conductive materials filled with fillers such as alumina and boron nitride, graphene-reinforced thermal conductive materials have high thermal conductivity, low density and good stability.
