Rogers Corporation’s RT/duroid 6035HTC is a high-thermal-conductivity fluoropolymer composite that contains a unique filler system, enabling a thermal conductivity of 1.44 W/m/K while maintaining low drill wear. The thermally stable material has a z-axis dielectric constant of 3.5 at 10 GHz, low loss by virtue of a loss tangent of 0.0013 at 10 GHz, and is available with … [Read more...]
Electrical Insulation Systems Standard
IEC/TS 62332-1:2011(E) is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a dual-temperature test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). The following significant technical changes with respect to the … [Read more...]

Companies Team Up to Develop Adhesives to Create 3D Semiconductors
3M and IBM plan to jointly develop the first adhesives that can be used to package semiconductors into densely stacked silicon “towers.” The companies are aiming to create a new class of materials, which will make it possible to build commercial microprocessors composed of layers of up to 100 separate chips. Such stacking would allow for dramatically higher levels of … [Read more...]
Yale Engineers Invent Magnetic Fluid Pump with No Moving Parts
In a study published today in Physical Review B, Yale electrical engineering professor Hur Koser and colleagues from the University of Georgia and Massachusetts Institute of Technology demonstrate for the first time an approach that allows ferrofluids to be pumped by magnetic fields alone. Their approach could lead to highly compact, integrated, quiet, and efficient liquid … [Read more...]
