The polymer, like many fluorine-containing polymers has very good weathering resistance and may also be used continuously up to 150°C. Outside of the electrical field it finds use in fluid handling, in hot water piping systems, in packaging and in chemical plant. A widely used specific application for PVDF is in ultra-pure water systems for the semiconductor industry.

Odor elimination is the additional benefit which has helped to drive the replacement of solvent-based systems. In packaging materials, most odors are related to the solvents used in inks, coatings and adhesives. Also, coalescing solvents from water-based systems caused odors. Elimination of solvent is a priority but solvent replacement may also change the response to the odor because solvents such as toluene and xylene smell like lubricating oils or turpentine whereas isopropanol smells more like a disinfectant. Odors stem not only from solvents but also from products of the thermal and UV degradation of other components and solvents. "...

One prerequisite for the combination of system-on-chip ( More Moore ) and system-in-package ( More than Moore ) to achieve higher-value systems is integration.

More functionality is achieved by further adding one or more ICs to the module. Fully functional blocks in one package are referred to as system-in-packages (SiPs). A vision of this is depicted in Figure 9.1.

FIGURE 58.5 System-in-Package (SiP) Module. SiP modules help reduce signal delay between a processor and the memory devices it communicates with. This SiP has one processor in the middle, surrounded by four discrete memory packages, all on one module. The module is soldered to the PWB via the solder balls on the back side of the module substrate.
