Techsil has launched a double-sided tapes range which is designed for bonding heat sinks on PCBs, LED strips and IC packages, mounting of ICs, GPUs, heat pipes and for heat sink assembly.
There are two thermally conductive tapes which not only allow heat to transfer easily and dissipate quickly but also provide a trustworthy bond. Stokvis 202331 and 202332 feature an acrylic adhesive which contains thermally conductive ceramic particles which transmit heat away from sensitive components.
Providing excellent thermal coupling between components and heat sinks - their foam-like, compliant interface means that they fill any air gaps thereby reducing the thermal resistance at the interface and can accommodate materials of different coefficients of thermal expansion. These double-sided tapes can be used in place of mechanical fasteners and are designed for bonding heat sinks on PCBs, LED strips and IC packages, mounting of ICs, GPUs, heat pipes and heat sink assembly.
Along with high thermal conductivity, the tapes also offer good heat resistance, age and weather resistance. These white, flame retardant acrylic foam tapes are halogen free and perform at intermittent temperatures of up to 150°C, with a continuous service temperature range of -40°C and +105°C - which means that electronic components can perform at the upper limits of their operating range for longer periods of time.
The thermal conductivity offered by Stokvis 202331 is 2 W/mK, with a breakdown voltage of 35 kV/mm. It offers adhesion on stainless steel of 25 N/25mm and a static shear (@ 23°C) of 1kg/625mm2. This grade comes in a 0.5mm thickness as standard, however if you're looking for a thicker alternative try Stokvis 202332 which is 0.8mm thick. 202332 still offers a high thermal conductivity of 1.2 W/mK, with a higher adhesion to steel of 30N/25mm.
