What are the application characteristics of thermal conductive double-sided tape?
Thermal conductive double-sided tape, also known as thermal conductive adhesive tape, is made of acrylic polymer mixed with thermal conductive ceramic powder, coated on both sides of glass fiber cloth, and compounded with organic silicone adhesive. It has high thermal conductivity and insulation properties, as well as certain flexibility, compressibility, adhesion, strong viscosity, and a wide temperature tolerance range.
Consistent with the working principle of thermal conductive silicone, thermal conductive double-sided tape is also filled on uneven surfaces, allowing the heat sink and heat source to tightly adhere to each other, transforming the original air thermal conductivity into the current thermal conductive double-sided tape.
Thermal conductive double-sided tape is widely used in bonding heat sinks, heat dissipation modules, CPU microprocessor heat dissipation, LED lighting heat dissipation, filling gaps between PCBs, metal components, and chassis. In addition to filling uneven surfaces, it also conducts heat away, and can be used even in enclosed spaces without changing any components, fully reflecting the thermal conductivity of this thermal conductive material and the convenient use of pressure-sensitive tape self-adhesive properties.
The operation of thermal conductive double-sided tape is simple and convenient, with high work efficiency. When using, simply peel off the release paper on the surface of the thermal conductive double-sided tape, and then gently press the adhesive surface onto the device surface to immediately bond. This eliminates the need for mechanical fixation and liquid adhesive curing between electronic components and heat sinks.
Thermal conductive double-sided tape can be divided into those with or without substrate according to the different materials used for production. It can also be divided according to the composition of the substrate, adhesive composition, etc. The main material composition is divided as follows:
1. There is a substrate or no substrate.
2. No substrate, cotton paper, PET, foam, non-woven fabric, cloth.
3. Water based acrylic ester, oil-based acrylic ester, solvent based rubber, hot melt adhesive, and organosilicon.
Characteristics of Thermal Conductive Double sided Adhesive
1. High thermal conductivity.
Superb heat transfer, conduction, and dissipation capabilities. The thermal conductivity of the double-sided adhesive tape is 0.8-1.0W/m.k, which solves the problem of difficult operation, uneven coating, and adhesive overflow caused by loose thermal paste, resulting in defective products.
2. Anti aging.
The working environment of thermal conductive double-sided tape is generally high temperature, high temperature, large temperature difference, and rich in ultraviolet rays. Therefore, it is required that the thermal conductive tape must be able to withstand low temperatures (below -20 ℃), high temperatures (above+120 ℃), and be able to resist long-term exposure to ultraviolet radiation. Working in various complex environments will not result in a decrease in thermal conductivity.
3. Replace mechanical operations such as rivets.
When traditional LED assembly is subject to considerations of human resource costs, reducing processes and improving products have become the choices of the LED industry. More and more LED companies are considering using thermal conductive double-sided tape to replace traditional mechanical operations such as rivets and screws. This not only serves as a fixing function, but also fully utilizes the role and function of thermal conductive double-sided tape.
4. Shock absorption function.
Thermal conductive double-sided tape is made by fully injecting air foam into acrylic (acrylic) substrate, and has shock-absorbing and shock-absorbing functions.
In today's era of continuous research and development in high technology, the thermal conductive material industry is also keeping pace with the times. In the electronics industry, thermal conductive double-sided tape plays a crucial role. Due to the difficulty of general thermal conductive materials in providing both thermal conductivity and good adhesion to important electronic parts, thermal conductive double-sided tape completely solves this problem; Especially in the fields of electronics, LED lighting, and LED television, it has played a significant role.
Faced with new requirements and technological challenges, the thermal conductive double-sided adhesive industry will usher in different changes. In today's increasingly developing world, thermal double-sided adhesive manufacturers rely not only on technology and quality, but also on service and reputation as a major competitive advantage.
