Properties and Applications of Thermal Tape
Thermal tape, also known as double-sided thermal adhesive tape, offers high thermal conductivity, strong adhesion, and low thermal impedance, making it an excellent thermal solution to replace traditional thermal grease and mechanical fasteners. It efficiently fills the uneven gaps between heat sources and metal components, ensuring optimal heat dissipation and heat management in electronic devices.
Types of Thermal Tape:
Thermal tape can be classified into two types:
- With Base Material: Reinforced with materials like glass fiber or polyimide to increase stiffness and dielectric breakdown voltage.
- Without Base Material: More flexible, ideal for less rigid applications.
Common components include acrylic-based and silicone-based pressure-sensitive adhesives:
- Acrylic-based adhesives: Suitable for porcelain and metal surfaces.
- Silicone-based thermal tape: Often used for plastic contacts.
Applications of Thermal Tape:
Thermal tape is widely used in:
- Chips on computer motherboards
- Small heat sinks for graphics cards
- Backlight module panels
- LED lamps
- ICs and other slender or small electronic components.
As electronic products have become more compact and efficient, the need for effective thermal solutions has increased. Today, high-performance chips and high-wattage LED bulbs require advanced heat dissipation methods, and thermal tape has become essential in applications like small thermal fins.
T-Global Technology continues to innovate and provide the latest thermal solutions to meet the evolving needs of the industry.
How to Use Thermal Tape:
- Measure the required area and cut the tape to fit.
- Peel off the backing and apply the tape smoothly between the thermal component and the heat sink.
- For larger heat sinks, use a fixing bracket to prevent detachment before the adhesive fully sets.
Key Considerations When Choosing Thermal Tape:
- Thermal conductivity
- Adhesion strength
- Flexibility
- High-temperature resistance
- Dielectric breakdown voltage
- Reinforcement materials
Advantages of Thermal Tape:
- Easy to use: Ideal for connecting LED chips and heat sinks, eliminating issues like uneven thermal grease application or excessive glue, which can cause defects.
- Efficient installation: Replaces screws and other mechanical fasteners, simplifying assembly and improving efficiency.
With its advanced thermal technology and growing demand, thermal tape has become a crucial thermal solution across industries. It helps effectively manage heat and ensures the long-lasting performance of electronic devices.
