Heat sinks are being used, but we want to improve heat dissipation.

Do you have any of these issues?

  • A heat sink is attached to an electronic component, but the temperature does not drop as much as expected.

Importance of heat dissipation

As electrical and electronic devices become smaller, lighter, and more powerful, thermal management of electronic components is becoming increasingly important.


Use without heat dissipation measures can lead to overheating and thermal runaway, which can cause equipment malfunctions and failures.


Heat Sinks

Problem Solution

Sanhayato's "Heat Dissipation Products" provide a solution!

However, even if electronic components (heat-generating components) and heat sinks (heat-dissipating components) are bonded together, there is an air layer in the microscopic world because of the unevenness and gaps between the surfaces (planes) of the bonded components. This air layer prevents sufficient heat dissipation.

By inserting Sanhayato's heat dissipation countermeasure product between the heat-generating component and the heat-dissipating component, the air layer can be filled and the heat dissipation effect can be improved.

Junction surface condition

Sanhayato offers a wide range of products to suit your application and performance.

List of Heat Dissipation Products by Application

Condition Type Product Features
Liquid, grease and clay products Grease type
(Non-hardening type)
  • Thermally Conductive Silicone
    (SCH-20 series)
  • Heat-resistant thermally conductive silicone
    (SCH-30 series)
  • Thin film coating is possible and thermal resistance can be reduced
  • Can be used for complex shapes
  • Can be reworked
Curing type
  • Thermally conductive RTV silicone
    (SCV series)
  • Thin film application is possible and thermal resistance can be reduced
  • Can be applied to complex shapes
  • No oil bleed
  • Parts can be fixed
Clay type
  • Clay type silicone for heat dissipation
    • Can be placed vertically without dripping like grease.
    • Does not pump out even at high temperatures.
    • No oil release, so it does not solidify like grease even after long-term use.
    Sheet products Adhesive type
    • Double-sided tape for heat dissipation
    • High thermal conductivity adhesive sheet
    • Easy to work with, just stick it on.
    • No oil bleed
    • Parts can be fixed
    Adhesive type
    • Thermal conductive sheet
      (HF-SC441, 443)
    • Easy to work with just by attaching
    • Can be used for uneven parts and multiple parts
    • Almost no oil bleed
    • Rework is possible

    In addition to improving heat dissipation, we also want to fix heat dissipating components (e.g. heat sinks)

    For use on heat-generating parts with uneven surfaces or bumps

    To be used in areas where reworkability is required

    Products using thermal radiation (thermal diffusion)

    The products introduced above utilize thermal conductivity, but there are also products that utilize thermal radiation (thermal diffusion).
    One such product is the heat sink (HF-C1225).

    Products utilizing thermal radiation (thermal diffusion)

    Features of the heat sink (HF-C1225)

    • Heat dissipation measures can be taken without using a heat sink by simply affixing it.
    • The sheet form allows for heat dissipation measures in a small space and weight reduction.
