Introduction to Thermal Conductive Absorbing Materials

Product Overview

Thermal conductive absorbing materialIt is a type of dual functional composite material that combines thermal management and absorption functions. This material can be used between integrated circuits, heat sinks, other thermal conductive components, and metal substrates, and this product not only solves the material problem. The problem of heat conduction can also suppress unnecessary electromagnetic energy coupling, resonance, and surface currents generated by electromagnetic interference. This material can be widely used in electronic components and devices such as communication equipment, network terminals, storage devices, consumer electronics, and power supply devices.

II Product Features

Thermal conductive absorbing materials not only reduce the electromagnetic interference of electronic components and equipment, ensure the stability of signal transmission, but also ensure the consistency of temperature stability and electrical performance. Due to its dual functions of thermal conductivity and absorption, this material provides a new solution for the design of electronic components, making it easy to design and assemble. It not only improves equipment stability but also reduces design and manufacturing costs.

IV. Instructions and Precautions for Use

Keep up withThermal conductive absorbing materialThe contact surface should be clean to prevent the thermal conductive absorbing material from sticking to dirt. The self adhesiveness and sealing thermal conductivity of the contaminated thermal conductive absorbing material will deteriorate.

Manual installation and use of thermal conductive absorbing materials: When taking thermal conductive absorbing materials, larger ones should be grabbed from the center, and smaller ones are not required because large pieces of thermal conductive absorbing materials are subjected to uneven stress, which can cause deformation, affect subsequent operations, and even damage the silicone film. Hold the sheet with your left hand and tear off one side of the release protective film with your right hand. Do not tear off both sides of the protective film at the same time to reduce the number and area of direct contact with the heat-conducting and absorbing materialThermal conductive silicone sheetSelf adhesiveness and thermal conductivity will not be compromised. Tear off one side of the protective film and face towards the heat sink. First, align the thermal conductive absorbing material with the heat sink. When slowly lowering the thermal conductive absorbing material, be careful to avoid the generation of bubbles. If bubbles are generated during operation, pull up one end of the silicone film and repeat the above steps, or gently wipe off the bubbles with a tool, without excessive force, to avoid damage to the thermal and absorptive materials. Remove the protective film on the other side and place it in the radiator. The force of removing the last protective film should be small to avoid pulling or pulling up the thermal conductive absorbing material. After fastening the thermal conductive absorbing material, apply a certain pressure to the radiator and store it for a period of time to ensure that the thermal conductive absorbing material is fixed properly.
