Properties and Applications of Thermal Tape

Thermal tape, also known as double-sided thermal adhesive tape, has high thermal conductivity, high viscosity and low thermal impedance, and can effectively replace thermal grease and mechanical fixing characteristics, and is used to fill the uneven gap between the heat source and the metal product, and bring the heat generated by electronic products away to achieve the effect of cooling and heat dissipation.
Thermal tape can be divided into those with base material and those without. The common components are acrylic-based and silicon-based pressure sensitive adhesive. The acrylic-based adhesive is suitable for porcelain and metal interfaces, while the silicone based thermal tape is commonly used for plastic contacts.
In addition, thermal tape is often reinforced with glass fiber or polyimide to increase stiffness and dielectric breakdown voltage. Thermal tape is commonly attached to small or slender electronic components, and is suitable for small chips on computer motherboards, small heat dissipation devices for video graphics cards, or panels for backlight modules due to its thermal conductivity and adhesive function.
In the early days, chips did not require heat dissipation devices, but as electronic products became more efficient and relatively smaller, the need for heat dissipation increased. As demand for heat dissipation grows, small thermal fins are used, and this is one of the most common applications for thermal tape. Nowadays, high performance electronic chips and high wattage LED bulbs require more heat dissipation, and the thermal solutions are evolving day by day.

How to use thermal tape:
1. Measure out the required area and cut it according to its length and width.
2. Tear off the film and stick it as smoothly as possible between the thermal product and the heat sink.
3. If the heat sink is large and heavy, it is recommended to use a fixing bracket to prevent the heat sink from falling off before the glue takes effect.
In addition to thermal conductivity and adhesion, the flexibility, high temperature resistance, dielectric breakdown voltage and reinforcement carrier used for products are also important factors in the selection of thermal tape.

Where can thermal tape be used?
Features: Good adhesion and thermal conductivity, easy to operate.
Applications: LED lamps, backlight modules, ICs, etc.
Advantages of thermal tape:
1.Easy to use for connecting LED chips and heat sinks, solving the problem of uneven application of thermal grease and excessive glue causing defective products.
2. Can replace screws, fasteners and other fixing methods.
