How to apply thermal pad?

Compared with thermal grease, thermal pad is a relatively new type of thermal interface material. It is a thermally conductive interface material processed by a special process using silica gel as the material, adding metal oxides and other auxiliary materials. The shape, soft and flexible, compressible, specially designed for the use of gaps to transfer heat, and also play the role of insulation, shock absorption, sealing and so on.

Nowadays, thermal pads have been widely used in computer mainframes, notebook computers, LED lamps, set-top boxes, routers, DVDs, new energy vehicles, power supplies, transformers, and other electronic and electrical industries that require filling and cooling modules. So how can thermal pads be used to effectively exert its thermal conductivity?

The following CoolThermo details the manual installation and use of thermal pads:

  1. Keep the contact surface with the thermal pad clean to prevent the thermal pads from sticking to dirt, and the dirty thermal pads will have poor self-adhesion and sealing thermal conductivity.
  2. When holding the thermal pads in hand, the thermal pads with a large area should be grasped from the center, and the grasping of the smaller-sized sheet is not required, because the uneven force of the large thermal pads will lead to the thermal pads. Deformation, affecting subsequent operations, or even damaging the thermal pads.
  1. Hold (support) the thermal pads in the left hand, and tear off one of the release protective films with the right hand. You cannot tear off both protective films at the same time, so as to reduce the number and area of ​​direct contact with the thermal pads, and maintain the self-adhesive and thermal conductivity of the thermal pads. Sex is not compromised.

Tips: Tear off the side of the protective film, facing the radiator, first align the thermal pads to the radiator, and be careful to avoid the generation of air bubbles when slowly lowering the thermal pads.

If bubbles are generated during the operation, you can pull up one end of the thermal pads and repeat the above steps, or use a tool to gently remove the bubbles. The force should not be too large to avoid damage to the thermal pads.

  1. Tear off the other protective film, put it into the radiator, and tear off the last protective film with less force to avoid straining or pulling up the thermal pads.​​
  2. After tightening or when using a strong adhesive thermal pads, apply a certain pressure to the radiator and store it for a period of time to ensure that the thermal pad is fixed well.

The above is a brief introduction to the manual operation of CoolThermo on how to use the thermal pads. You can refer to it in actual operation. At the same time, you should constantly sum up experience in the actual operation process, which is conducive to improving the operation efficiency and ensuring the thermal pads. The performance of the performance, but also hope that everyone can sum up new experience and share.
