Key performance parameters for thermally conductive double-sided tape include thermal conductivity, thermal impedance, thickness, bond strength, volume resistivity, and operating temperature range. Typical thermal conductivity ranges from 0.8 to 1.6 W/m·K, while thermal impedance falls between 0.25 and 1.28 °C·in²/W. Common thickness specifications include 0.1 mm, 0.15 mm, and 0.25 mm, with an overall range of 0.1 to 0.5 mm. Regarding bond strength, lap shear strength can reach 70 psi (0.483 MPa) or exceed 10–13 N/in. The material exhibits a volume resistivity greater than 10¹³ Ω·cm and an operating temperature range of -20°C to 180°C, with the ability to withstand short-term exposure to temperatures up to 288°C.
Testing protocols for thermally conductive double-sided tape primarily cover viscosity, peel strength, shear strength, impact resistance, aging performance, salt spray testing, environmental compliance, and compositional analysis. Relevant product certifications include the QOQW2 adhesion certification from UL (Underwriters Laboratories). Testing may be conducted in accordance with standards such as GME STD 518784-1996 (for double-sided adhesive tape) and FORD WSB-M3G205-A-2006 (for high-temperature modified PVC tape).
During bonding tests and applications, it is essential to ensure that bonding surfaces are clean and free from contaminants such as oil or grease. After bonding, pressure should be applied and maintained for a specific period to facilitate initial adhesion.
