Synthesis of siloxane-containing epoxy polymers Patent
Synthesis of siloxane containing epoxy polymers with low dielectric propertie
Improved printed-wiring boards for high-reliability circuits
Experimental board includes three layers of special tridirectionally woven fabric. Alumina particles play major role in reducing coefficient of expansion. They also serve as heat sink for heat-generating components
Alpha particle backscattering measurements used for chemical analysis of surfaces
Alpha particle backscattering performs a chemical analysis of surfaces. The apparatus uses a curium source and a semiconductor detector to determine the energy spectrum of the particles. This in turn determines the chemical composition of the surface after calibration to known samples
