熱伝導材料を理解する
Thermal Interface Materials are specialized substances designed to enhance heat transfer between electronic components (heat sources) and heat sinks. When two surfaces meet, microscopic air gaps naturally form between them due to surface irregularities. These air pockets act as insulators, significantly reducing heat transfer efficiency. TIMs fill these gaps, creating an optimal thermal path that enables efficient heat dissipation.熱伝導材料の種類
