A very general question within this modular concept is the choice of circuit board and connection technology. Each pathway in Figure 5.8.7 corresponds to a possible way of building a sensor. Metal packages can be welded directly onto metal inlay parts, and ceramic modules can be directly bonded. All the illustrated modules contain a printed circuit board (PCB). 

The concept of compatibility asserts that any material applied to an object should be compatible with it, i.e. its properties should be as close as possible to eliminate future stresses. The problems that appear when different materials are put together in an object are illustrated by many of the museum objects that present conservation problems today. Consider, for example, an object that has a metal inlay in wood, as compared to stone inlay in stone. The latter has far fewer problems than the former, precisely because their properties, such as expansion coefficients upon heating or during changes in relative humidity, are similar. 

The primary use of silver(I) sulfide is in the production of glazes for ceramics. The compound gives a glassy or metallic sheen to the glaze. It is also used in the process known as niello, first used by the early Greeks and Romans to produce a black, metallic inlay on the surface of pottery. 

The resulting multilevel structure comprises a series of planar metallic layers with metal inlays in the dielectric, forming the circuitry (see Fig. 16.20). Figures 16.21 and 16.22 show SEM micrographs of a cross section of a 90-nm technology node AMD microprocessor, with nine copper metal layers, fabricated with dual damascene copper interconnect technology. 

Skiving is a variant in which the base metal surface oxides are mechanically removed foUowed immediately by pressure rolling of a precious metal or alloy strip. This is commonly used for inlays for electrical contacts and for jewelry fabrication. The common inlay materials include gold, silver, copper, brass, and solder. No heat is needed, and the coating is appHed only to designated areas so there is Htde waste (3,50). 

The use of this nigello emphasized by Theophilus is for inlaying metal articles in decorative patterns and the method of application is also described in detail.

Lacquer was probably first used solely as a protective coating decorative elements have evolved with time. Objects may be simply colored in monochromatic red or black, for example, Chinese bowls and carved boxes. Other objects may be highly ornate, with patterns introduced by using metal flakes or foil to produce decorations on the interior subsurface layers. Some pieces may have designs of inlaid mother of pearl still others have a combination of metal-flake patterns and mother-of-pearl inlay. It is common for some objects to have 60-100 individual layers. Hardening and polishing each layer takes from several days to months it might require many years for completion of an article. 

Q A mountain climber breathes from a container of compressed oxygen gas, a nonmetal. This Persian brass bowl contains inlays of the transition metals silver and gold. Q Silicon crystals, a metalloid, are grown in an inert atmosphere of argon, a nonmetal. The crystals are used in the manufacture of computer chips. 

Gold has found many industrial uses because of its excellent electrical and thermal conductivity properties. It is used for plating other metals and as an alloying metal. It is used in the manufacture of jewelry, dental inlays, art, currency, electronic components, and in some medical devices to provide radio opacity. Gold compounds have also found use in medicine in the treatment of certain cancers, rheumatoid arthritis, discoid lupus (a rare skin disease), and in specialized surgical procedures. 

Another type of discomfort results when a less electropositive metal touches a dental filling. For example, if a filling makes contact with a gold inlay in a nearby tooth, corrosion of the filling will occur. In this case, the dental filling acts as the anode and the gold inlay as the cathode. Referring to the P values... 

The preceding research on the model maxillofacial material was followed by TMDSC study of several representative elastomeric impression materials, which are extensively used in dentistry for the accurate fabrication of inlays and crowns from dental alloys, metal-ceramic restorations, and fixed and removable partial dentures [1-3]. There have been numerous studies reporting the clinically relevant properties of these impression materials (viscosity before setting by polymerization, strain in compression after setting, permanent deformation for simulated in vivo removal of the impressions, and tear strength of the thin impressions). However, only minimal research has been reported [44] on some thermal properties of impression materials obtained by conventional DSC. Our pioneering TMDSC study [45] was designed to obtain fundamental information about impression materials and seek correlations with their relevant properties.
