Miniaturization electronic components

Continued advances in analytical instmmentation have resulted in improvements in characterization and quantification of chemical species. Many of these advances have resulted from the incorporation of computer technology to provide increased capabilities in data manipulation and allow for more sophisticated control of instmmental components and experimentation. The development of miniaturized electronic components built from nondestmctible materials has also played a role as has the advent of new detection devices such as sensors (qv). Analytical instmmentation capabiHtieSj especially within complex mixtures, are expected to continue to grow into the twenty-first century. 

Production systems produce physical products efficiently and at the lowest cost possible. We use these systems to produce all kinds of products— from food that you or your pet eats to miniature electronic components that will become part of a consumer product like a video game. We can subdivide production systems into manufacturing and construction depending on whether a product is built off-site or on-site. Manufacturing usually involves making multiple pieces in a plant. Construction typically involves building a single structure on-site. For example, we could manufacture a house in a plant and then deliver it to the site to be set on a foundation. Or we coifld construct (build) the house on a foundation at the site. 

Wearable technologies have become extremely developed over the years in the textiles industries (Microsoft, 2015 CNET, 2015 Samsung, 2015). Most of them focus on the development of wearable equipment such as watches and glasses to help wearers to communicate and acquire data. The world is aware of the importance of wearable devices and their huge market and business value. Portability, invisibility, flexibility, and feasibility have become the trends of electronic devices. In the apparel industries, research has started to integrate miniaturized electronic components into textile fabrics (Google, 2015). Google and Levi Strauss have started a special project called Project Jacquard with the industries to fabricate jeans that can connect with a computer, tablet, or telephone. 

The objective is to seamlessly integrate electronic devices into textiles. All efforts are being made to realize that objective in the fields of new materials, nanotechnology, and miniaturized electronic components. The ultimate aim is to let users accept electronically functionalized products without feeling a difference in the mechanical properties and hand feel of the materials.

In a final molded part, PET and PBT have exceptionally low moisture absorption and a low coefficient of thermal expansion. This gives them excellent dimensional stability over a broad temperature range. When proper molding controls are implemented, PET and PBT parts can be molded with exceptional precision. This makes them excellent candidates for miniature electronic components. 

One successful total artificial heart is ABIOMED s electric TAH. This artificial heart consists of two seamless blood pumps which assume the roles of the natural heart s two ventricles (Fig. 7). The pumps and valves are fabricated from a polyurethane, Angioflex. Small enough to fit the majority of the adult population, the heart s principal components are implanted in the cavity left by the removal of the diseased natural heart. A modest sized battery pack carried by the patient suppHes power to the drive system. Miniaturized electronics control the artificial heart which mns as smoothly and quietly as the natural heart. Once implanted, the total artificial heart performs the critical function of pumping blood to the entire body (6). 

The main reason for the tantalum industry s drive toward the sodium reduction process is an increasing demand for tantalum powder by tantalum capacitor manufacturers. The modem tendency of the electronics industry to miniaturize their components calls for the improvement of tantalum powder... 

The basic steps of the IM process produce unique structures in all molded products, whether they are miniature (micro) electronic components, compact discs, or large automotive bumpers. These structures have frequently been compared to plywood with several distinct layers, each with a different set of properties. In all IM products, a macroscopic skin-core structure results from the flow of melt into an empty cavity. Identifiable zones or regions within the skin are directly...

The miniaturized Mossbauer instruments have proven as part of the NASA Mars Exploration Rover 2003 mission that Mossbauer spectroscopy is a powerful tool for planetary exploration, including our planet Earth. For the advanced model of MIMOS II, the new detector technologies and electronic components increase sensitivity and performance significantly. In combination with the high-energy resolution of the SDD, it will be possible to perform XRF analysis in parallel to Mossbauer spectroscopy. In addition to the Fe-mineralogy, information on the sample s elemental composition will be obtained. 

In 1958, Jack Kilby (1923-2005), a researcher atTexas Instruments, invented a miniature electronic circuit known as an integrated circuit. Modern integrated circuits, which contain many electronic components etched on a thin wafer of silicon, have become a vital part of many devices, especially computers. Placing a large number of electronic components in such a small area has greatly reduced the size of electronic equipment. 

Microminiature drug delivery device. This is the heart of the implanted medication systems. The drug delivery device often consists of a diaphragm-operated infusion pump that supplies drug at a constant predetermined rate to the body. The pump is connected to the drug reservoir, which, in some cases, may be recharged when exhausted. Today, the available electronic components are so miniature that they can be implanted comfortably even in newborn babies. The pump can be programmed for a constant or variable basal infusion of medication with a repetitive period of from 1 hour to 60 days. By far the most frequently used basal period is 24 hours. A period of 28 days is available, particularly for the infusion of sex hormones to mimic the female menstrual cycle. 

Thermal Conductivity. Many of today s electronic products feature miniaturization. In these applications, higher thermal conductivity and better dimensional stability are required from adhesive systems. Thermal management has become a significant area of development, and thermally conductive adhesives provide a way to transfer heat away from sensitive electronic components.
