    Abstract: A semiconductor chip packaging structure comprising a dielectric film 1 0 having one or more through holes 11 aligned with the one or more contact pad s 22 and 23 of at least one power semiconductor chip 21. A patterned electrically conductive layer 40 adjacent to the dielectric film 10 has one or more electrically conductive posts 41 which extend through the one or more though holes 11 aligned with the contact pads 22 and 23 to electrically couple the conductive layer 40 to the contact pads 22 and 23. In certain embodiments, one or more air gaps 91 may be formed betwee n the dielectric film 10 and the active surface 24 of the at least one power semiconductor chip 21. Methods for fabricating the semiconductor chip packaging structure are also disclosed.

    Abstract: Thermal interface compositions contain both non-electrically conductive micron-sized fillers and electrically conductive nanoparticles blended with a polymer matrix. Such compositions increase the bulk thermal conductivity of the polymer composites as well as decrease thermal interfacial resistances that exist between thermal interface materials and the corresponding mating surfaces. Such compositions are electrically non-conductive. Formulations containing nanoparticles also show less phase separation of micron-sized particles than formulations without nanoparticles.

    Abstract: Una lámpara fluorescente incluye un tubo de lámpara que tiene primero y segundo extremos y que contiene materiales de relleno para ocasionar la generacion de luz cuando se proveen con energía eléctrica. La lámpara demás incluye primeros y segundos medios de transferencia de energía en los primero y segundo extremos del tubo de lámpara, respectivamente, para proveer los materiales de relleno, en el tubo de lámpara, con energía eléctrica. También se incluye un blindaje térmico separando los primeros medios de transferencia de energía del circuito de balastra, el cual suministra energía a los primeros medios de transferencia de energía y el cual tiene una duracion que se vuelva substancialmente menor a medida que su temperatura de operacion se incrementa. El blindaje térmico está construido de manera que se refleja de regreso a los primeros medios de transferencia de energía y cualquier porcion adyacente del tubo de lámpara suficiente para que la energía radiante reduzca la temperatura de operacion del circuito de balastra por más de aproximadamente 1 degree C, comparado con la ausencia de dicho blindaje térmico.

    Abstract: Se describen composiciones de interfase termicas (10) que contienen tanto llenadores micronizados electricamente no conductores (18) como nanoparticulas electricamente conductoras (20) mezcladas con una matriz de polimero (16). Dichas composiciones incrementan la conductividad termica volumetrica de los materiales mixtos de polimero asi como reducen las resistencias interfaciales termicas que existen entre materiales de interfase termicos y las superficies coincidentes correspondientes. Dichas composiciones son electricamente no conductoras. Las formulaciones que contienen nanoparticulas (20) tambien muestran menos separacion de fase de particulas (18) con un tamano de micra que las formulaciones sin nanoparticulas (20). Los metodos para incrementar la transferencia de calor incluyen utilizar dichas composiciones entre componentes de produccion de calor (12) y colectores de calor (14). Tambien se describen componentes electronicos que utilizan dichas composiciones.
