Thermally conductive adhesive tapes serve as both, a part of thermal management system, and mechanical stability structure. The common usage of these tapes involves adhering LED lights and semiconductor packages for heating the sink surfaces.
Such tapes only need pressure to achieve the complete potential. These tapes can also be used as a substitute of mechanical attachment hardware such as screws, and springs that reduces the installation time and costs.
The rising demand for miniaturization, and automation of electronic devices and medical devices boost the demand for thermal interface materials.
As electronics are becoming smaller, and components get more concentrated, the chances for them getting heat up are more. It thus, increases the heat density over the electronic equipment surface. Therefore, the thermal interface materials are required for providing the heat dissipation.
Pastes, Putties, Greases, and Gels
Thermal greases, putties, pastes, and gels are produced in a fluid state at a room temperature. They offer consistency similar to soft butter or toothpaste.
Several products are designed to become harder or provide rubber consistency after being applied. While, several remain as fluid in their entire life cycle.
Grease is sold as a non-curing product in the market, and applied in thin layers to facilitate the thermal transfer between smooth and flat surfaces.
Moreover, putty is used to improve the thicknesses. It fills the gap present between the irregular or unusual surfaces, without touching one another.
Such products are electrically non-conductive in nature. Several can be designed to be conductive, and may cause problems if bridge nodes are not connected in the circuit.
The phase-change materials transform themselves from a solid-state to a viscous liquid at lower temperatures. It usually happens in a range of 131-149 degrees Fahrenheit.
The phase-changing property enables handling and processing materials at a solid form in room temperature, while it acquires wetting and comfortability fluid properties at elevated operating temperatures.
Moreover, PCMs do not get messy during manual assembly process, as they usually suffer from dry-out issues. They can be pre-applied for future assembly applications.
Furthermore, they have lower misapplication tolerance due to their expensive cost. PCMs come in various forms, such as sheets, bulk rolls, and shapes pre-cut from same form to get fitted in device packages, deodorant such as sticks, and dispensable sticks. The dispensable fluids get harden or dry when they come to a solid phase-changing state after its foremost application.
Potting Compounds and Liquid Adhesives
The thermal potting compound provides protective encapsulation. It happens while enabling the heat transfer from innards to outer shell of the system. These can be bought in fluid form.
Products usually sold as fluids usually possess several adhesive and mechanical properties after getting cured. Several may barely stick to surface during their application, and can easily be peeled away. Several may offer moderate adhesion, while others offer permanent adhesion.
The major players operating in the industry are; Henkel AG & Co. KGaA, Dow Corning Corporation, Parker Hannifin Corporation, Laird Technologies, Indim Corporation, Momentive Performance Materials, and Wakefield-Vette.
Therefore, the miniaturization of the electronic and medical devices boosts the demand for thermal heat dissipation materials.
