INDUSTRY COMPONENT

Thermal pad

Thermal interface material for heat dissipation in LED arrays

Component Specifications

Definition
A thermally conductive pad used to transfer heat from LED chips to heat sinks or substrates in LED array modules, filling microscopic air gaps to improve thermal conductivity and prevent overheating.
Working Principle
Works by conforming to surface irregularities between heat-generating components and cooling surfaces, providing a continuous thermal pathway through its conductive matrix to dissipate heat via conduction.
Materials
Silicone-based polymer filled with thermally conductive ceramics (e.g., boron nitride, alumina) or metal oxides; may include fiberglass or polyimide reinforcement.
Technical Parameters
  • Hardness 20-80 Shore 00
  • Thickness 0.5-5.0 mm
  • Dielectric Strength >5 kV/mm
  • Thermal Conductivity 1.5-12 W/mK
  • Operating Temperature -40°C to 200°C
Standards
ISO 22007-2, ASTM D5470, DIN 53430
