Providing thermal coupling between components and heat sinks, their foam-like interface means that they fill air gaps, reducing the thermal resistance 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, Stokvis 202331 and 202332 also offer heat resistance, age resistance and weatherability. These tapes are said to perform at intermittent temperatures of up to 150°C, with a continuous service temperature range of between -40 and 105°C, meaning that electronic components can perform at the upper limits of their operating range for longer periods of time.
