GTA thermal gap pads provide thermal interfaces between electronic components and heat sinks, helping accommodate gaps and surface irregularities for improved thermal contact. The portfolio includes silicone-based thermal pads, silicone-free / silicone-oil-free thermal pads, and phase-change thermal pads (PCM), offering options for different modules, assembly processes, and reliability requirements.
Three Thermal Pad Material Platforms
Silicone-Based Thermal Pads
Soft and compressible materials that accommodate component height differences and assembly gaps; commonly used in 5G communication, automotive electronics, and PCB modules.
Silicone-Free / Silicone-Oil-Free Thermal Pads
Material options for applications sensitive to silicone-related contamination, such as optical communication modules and IC packaging; process compatibility and reliability should be verified.
Phase-Change Thermal Pads (PCM)
Maintain a sheet-like form at room temperature and gradually soften as operating temperature rises, improving conformity to microscopic surface irregularities in CPU/GPU, server, and cold-plate interfaces.
Selection considerations: gap size, contact pressure, thermal conductivity, actual interfacial thermal resistance, compression / phase-change behavior, and contamination-control requirements should be evaluated under the intended module conditions.
