The Balance of Soft and Hard: Deep Dive into Shore Hardness and Compression Force Deflection (CFD) of Thermal Silicone Pads

hardness-silicone-lixing

In thermal design, many engineers tend to choose the “softest” pad, assuming it guarantees the lowest interfacial thermal resistance. However, material hardness (Shore Hardness) and Compression Force Deflection (CFD) represent a dynamic mechanical balance that directly impacts assembly stress and long-term reliability. A thermal silicone pad with the appropriate hardness achieves perfect gap-filling at extremely […]
