In power electronics and power supply designs, thermal interface materials (TIMs) must handle more than just heat; they must survive mechanical stress during assembly. Standard thermal pads are prone to puncture by metal burrs under high torque. Thermal Conductive Silicone Cloth solves this by integrating fiberglass reinforcement with high-performance silicone.
Material Science: Composite Structure and Dielectric Strength
-
Fiberglass Reinforcement & Tear Strength: The core of this material is the “E-glass fiber cloth.” Under screw pressure P, the mesh distributes stress to prevent localized tearing. Tear Strength (Ts) is defined as: Ts = F / d (Pure text: Ts = F / d, where F is the maximum force before failure and d is the thickness)
-
High Voltage Insulation & Dielectric Breakdown: In applications like TO-220 packages, the cloth must block kilovolts of electrical potential. The dielectric strength E is modeled as: E = V_breakdown / d (Pure text: E = V_breakdown / d, where V_breakdown is the voltage at failure) Lixing’s silicone cloth provides >6kV/mm protection, ensuring safety during voltage spikes.
-
Thermal Flux Stability: Despite the fiber mesh, advanced coating technology ensures low interfacial resistance. Heat transfer follows Fourier’s Law: Q = k * A * (dT / d)
Industrial Applications
-
High-Power SMPS: Applied between MOSFETs and heatsinks for insulation and cooling.
-
On-Board Chargers (OBC): Maintains structural integrity and electrical isolation in high-vibration automotive environments.
