Editors tend to frown on use of "revolutionary" in technical papers. However, advances in thermal management material properties in the last few years clearly warrant this word. There are now over a dozen materials with low coefficients of thermal expansion (CTEs) and thermal conductivities higher than that of copper (400 W/m K), and a score with thermal conductivities at least … [Read more...]
High performance thermal management materials
Various new advanced composite materials are now available, which provide great advantages over conventional materials for electronic packaging thermal control, including: Extremely high thermal conductivities (up to twice that of copper) Low, tailorable coefficients of thermal expansion Extremely high strength and stiffness Low densities Low cost, net shape fabrication … [Read more...]
