Abstract: Methods of classifying tobacco include imaging tobacco with an imaging system to obtain an image and classifying the tobacco as very low nicotine (VLN) or traditional based on the obtained image. The imaging system includes a hyperspectral camera and an image processing system.

Abstract: A printed wiring board laminate is disclosed that is particularly suitable for use with leadless surface mounted devices such as ceramic chip carries. The laminate combines a low coefficient of thermal expansion in the X-Y direction with thermal conductivity. In one embodiment, the laminate comprises a support fabricated from graphite fiber reinforced metal adhesively secured to a printed wiring board fabricated from dielectric (e.g., glass) fiber reinforced resin. The support has an X-Y coefficient of thermal expansion less than about 4 ppm/.degree.C., and the printed wiring board has a coefficient of thermal expansion greater than about 10 ppm/.degree.C. In a second embodiment, the support comprises a core of graphite fiber reinforced metal or resin sandwiched between two metal sheets.
