WHAT ARE THERMAL INTERFACE MATERIALS?
A thermal interface material (TIMs) describes any material that is inserted between two parts in order to enhance the thermal coupling between these two components. A majority of applications are related to the heat dissipation of the system. The TIM is inserted between the heat producing device (the heat source) and the heat dissipation device (heat sink).
Challenges manufacturers face include:
- Numerous types of TIMs
- A wide variety of products within each type
- Limited technical knowledge to select the right solution
- Difficulty finding a reliable supplier
THERMAL INTERFACE MATERIALS THEORY
Heat will always be transferred from a hot medium to a cold medium:
WHY DO WE NEED TIMS?
The rough machined surfaces of a heat sink and heat source result in limited contact points.
Bringing the rough surfaces closer creates insulating air gaps, causing contact resistance and thermal barriers.
A thermal interface material (TIM) fills voids, replaces air with a higher conductivity material, and improves surface contact for better heat transfer.
BENEFITS OF THERMAL INTERFACE MATERIALS
Reduce thermal impedance across gaps
Replace air with more thermally conductive materials
Conform to surface irregularities
Electrical isolation
Attachment
TYPES OF THERMAL INTERFACE MATERIALS
What is thermal pad?
Thermal Pads (also called thermally conductive pads) are a preformed square or rectangle of solid material (often silicone-based) commonly used on the underside of the heatsink to aid the conduction of heat away from the component being cooled (such as CPU or another chip) and into the heatsink.
FEATURES
- 0.5 – 24 W/mK thermal conductivity
- 0.2 – 12 mm thickness
- 2 – 10 kV/mm breakdown voltage
- Silicone or Silicone free
BENEFITS
- Soft & conformable to fit uneven & rough surface area
- Providing low stress on components during assembly while providing shock-dampening abilities
- Providing easier handling abilities for simple application & automated assembly
- Offering puncture, shear & tear resistance for added device resilience
- Cut to the desired size and shape
FEATURES
- Typically composed of a carrier material, such as polymer, embedded with thermally conductive fillers like ceramic or metal particlesThermal conductivities of around 1-2 W/mK
- Thin material
BENEFITS
- Electrically insulating
- Good adhesion is perfect for fastening mechanical components
- Low thermal impedance
- Easy to apply
- Cut to the desired size and shape
What is Phase Change Material?
Phase change material (PCM) refers to a substance that changes the state of a substance and provides latent heat without changing the temperature. The process of transforming physical properties is called a phase change process. At this time, the phase change material will absorb or release a large amount of latent heat.
FEATURES
- Typically made from natural or synthetic graphite
- Excellent thermal conductivity in the horizontal XY-plane (up to 1800 W/m-K)
- Can be laminated with adhesive layer
- Cut to desired size & shape
BENEFITS
- Can handle high temperatures and thermal cycling, this makes them suitable for use in high-power applications
- Highly flexible and conformable
- Simply process
What is Graphite/Graphene sheet?
Thermally Conductive Graphite is a TIM with high thermal conductivity and a thin graphite film structure (thickness measured in microns). Graphite is formed of a layered structure with strong covalent bonds within the layers, and weak van der Vaals bonds connecting the layers.
What is Thermal Grease?
Thermal grease is a type of material that is used to improve heat transfer between two surfaces that are in contact with each other. Thermal grease is typically made up of a mixture of thermally conductive fillers, such as aluminium oxide, silicon dioxide, and boron nitride, suspended in a carrier fluid, such as a silicone oil or water. The fillers are chosen to maximize thermal conductivity while minimizing electrical conductivity to avoid shorting out the electronics.
FEATURES
- Either silicone or non-silicone based
- Non-silicone putties tend to have good stability and longevity compared to silicone formulas and are advisable in silicone sensitive applications
- It can be messier to apply and more difficult to remove
BENEFITS
- A soft, mouldable material that is used to fill gaps and uneven surfaces
- Strong thermal conductivity and electrical insulation properties
- Offers good resistance to thermal cycling and maintains strong levels of thermal conductivity
- Suited for high volume application
What is Thermal Gap Filler?
Gap fillers are thermally conductive gap filling liquid materials designed to enhance thermal performance and enable easier dispensing application for your high-volume manufacturing operations.
FEATURES
- Two-part material
- Are frequently utilized in markets such as automotive, where high reliability is required
BENEFITS
- Ultra-low modules for minimal stress during assembly
- Excellent conformability to intricate geometries
- Single solution for multiple applications
- Efficient material usage
- Customizable flow characteristics
