Modern computer-generated heat is emitted primarily through the upper surface of the assembly, so low thermal resistance at the junction is important to the proper operation of the radiator. LED with its small size, low power consumption, environmental protection, strong and durable light source color, and other characteristics, by the majority of users of the favor. However, one of the bottlenecks in the development of LED lighting is heat dissipation, which can be solved with thermally conductive adhesive. 1. Heat conducting glue can improve the performance of the radiator. When the sizing method is reasonable, the thermally conductive adhesive fills the space between the radiator and the heat source. The gap-filling is very important. If the glue doesn't fill, the heat is prevented from spreading, and money has to be spent to repair or replace it. 2. The heat conduction adhesive can ensure the stability and reliability of the required temperature and technical parameters. For example, you can actually brush the surface of glue and catalyst to achieve the desired effect without degrading the bonding surface. Besides, the thermal conductive adhesive is easy to use, can self-leveling, does not need to pretreat the surface, therefore, product cost and sizing time are greatly reduced. 3. Fast curing two-component thermal conductive adhesive can effectively bond electronic components and radiators without mechanical devices. These acrylate structural adhesives have a substantial cost advantage over mechanical fixtures, and this frequent positioning requirement tends to add additional costs during production and assembly. The components can be firmly bonded with the heat-conducting adhesive solidified at room temperature, which can not only cool the vertical plane but also cool the metal shell and the side plate without the installation of chips, screws, or other mechanical positioning devices. Acrylate thermal conductive adhesives can also replace mechanical devices and contaminate silicone grease. 4. Some electronic parts, such as the master videotape processor, should not be punched or installed with clamps and rivets to fix the radiator. Thermal conductive adhesive is an ideal solution in this case. Adhesives not only provide the mechanical strength of the bond between the radiator and the heat source but more importantly, they fill all the gaps and remove the air (insulation) between the parts. 5. Thermal conductive adhesive can also bond to a wide range of materials, even on soiled or greasy surfaces. The vibration test of 10g showed no adverse effects of bonding. The thermally conductive adhesive also has high peel strength and high impact strength, strong bond, durable, anti-vibration. After a wide range of environmental temperature and humidity testing and aging experiments, the thermally conductive adhesive not only fully meets the requirements but actually far exceeds the original thought of the tensile strength and thermal conductivity of the basic characteristics. Traditional thermal adhesive packaging applications include chip welding, installation of heat sink microelectronic packaging, sensor packaging. Also, with the development of electronics and power engineering, LED lights, solar energy equipment, heat exchangers and auto parts, more and more new power electronic equipment has different needs than ever before. Thermal conductive adhesives have a wide range of applications in these products. In addition to meeting different mechanical properties, they also have unique requirements and challenging process parameters, such as adhesives that can connect components with mismatched thermal conductivity.
