In modern electronics, thermal management materials must deliver not only high conductivity but also exceptional mechanical stability. Many thermal failures occur not because of a drop in thermal conductivity, but due to Compression Set under long-term thermal pressure, leading to micro-gaps at the interface. Understanding the viscoelastic nature of Thermal Silicone is vital for ensuring […]

In thermal system design, the performance of a thermal pad(gap pad) is determined not just by its bulk conductivity, but by its rheological behavior under assembly pressure. Achieving the minimum thermal resistance without compromising PCB mechanical integrity is a critical engineering challenge. Physicochemical Principle: Percolation and Particle Alignment Thermal pads consist of high-elasticity silicone matrices […]
