In 5G telecom and high-performance computing, the efficiency of heat transfer hinges on the interfacial material. Thermal Pads are engineered to eliminate micro-air gaps via physical deformation, drastically reducing the total system resistance.
Material Science: Interfacial Wetting and Phonon Transport
-
Total Thermal Resistance Model: The compliance of the pad determines its “wetting” ability. Total resistance (R_total) is expressed as: R_total = (L / k) + Rc (Pure text: R_total = (L / k) + Rc, where Rc is the interfacial contact resistance)
-
Phonon Conduction:Thermal Pads utilize high-loading ceramic fillers to create conduction paths. Thermal conductivity (k) follows Fourier’s Law: k = (Q * L) / (A * dT) (Pure text: k = (Q * L) / (A * dT))
-
Low Bleed-out Chemistry: Lixing utilizes long-chain siloxane cross-linking to lock silicone oils into the matrix, ensuring TML < 0.1%.
Industrial Applications
-
5G Remote Radio Units (RRU): Reliable heat transfer under high vibration.
-
Optical Sensors: Prevents siloxane deposition on sensitive lenses.
