INDUSTRY COMPONENT

Thermal Interface Pad

Thermal interface pad for efficient heat transfer between heat sink and heat source in industrial equipment.

Component Specifications

Definition
A thermally conductive, compressible pad designed to fill microscopic air gaps between mating surfaces of heat sinks and heat-generating components, ensuring optimal thermal conductivity and electrical insulation in industrial-grade aluminum heat sink assemblies.
Working Principle
Operates by conforming to surface irregularities under compression, displacing insulating air pockets with thermally conductive material to create a low-thermal-resistance path for heat dissipation from electronic components to the heat sink.
Materials
Silicone polymer matrix filled with ceramic (aluminum oxide, boron nitride) or metal oxide particles, reinforced with fiberglass or polyimide film for structural integrity.
Technical Parameters
  • Hardness 20-80 Shore 00
  • Thickness 0.5-5.0 mm
  • Compression Set <20%
  • Dielectric Strength >4 kV/mm
  • Thermal Conductivity 1.5-12 W/m·K
  • Operating Temperature -40°C to 200°C
Standards
ISO 22007-2, ASTM D5470, DIN 53479

Frequently Asked Questions

How does a thermal interface pad differ from thermal grease?

Thermal pads are solid, pre-formed sheets that provide consistent thickness and electrical insulation, while thermal grease is a paste that requires precise application and can pump out under thermal cycling.

What maintenance is required for thermal interface pads?

Pads typically require replacement during component servicing due to compression set degradation; they should be inspected annually in high-temperature applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
