Conductive high purity adhesive

Conductive adhesives are used for many other electronic assembly operations, in addition to die attach. Epoxy paste adhesives are used for capacitor and other component attach in hybrid components or on printed circuit boards. In general, these electronic assemblies require high purity adhesives which do not give off im-... [Pg.710]

First use of electrically conductive epoxies Premixed, frozen adhesives introduced by Ablestik Laboratories, Epoxy Technology, and Amicon Reduced ion content epoxies and polyimides Introduction of epoxy preforms First high-purity RTV silicone adhesives from G.E. and Dow Coming... [Pg.28]

The electrical properties, especially for the high-purity semiconductor-grade silicones, are excellent even at temperature extremes of —80 °C and 200 °C and in high humidity. Silicone adhesives are available as electrically conductive and as electrically insulative types. Typical electrical properties for moisture- and heat-cured silicone adhesives are given in Table 3.12. [Pg.126]

The resins, solvents and curing agents used in modem conductive epoxy adhesives are chosen to minimize residual vapors which can be released after cure. Modem epoxy adhesives generally consist of high purity Bis-A epoxies cured with a phenolic novolac resin. These mixtures do not contain boron or fluorides, and generate less ammonia or other corrosive vapors than epoxies available before 1982. [Pg.712]

Recently, the major U.S. and Japanese resin manufacturers have made available new, highly purified epoxy resins which contain much less extractable and hydrolyzable chlorides than the best epoxy resins prior to 1980. Adhesive for-mulators now use these high purity epoxy resins to produce conductive adhesives, coatings, and encapsulants which yield chloride levels of 10 ppm or less and sodium levels of 5 ppm or less. [Pg.712]

Sauereisen s adhesives and potting compounds are inorganic, ceramic-based materials. These specialty cements are composed of high-purity, inert fillers such as silica, alumina, or zircon. The nature of these materials, when formulated in a dense matrix with an appropriate binder, is to exhibit high thermal conductivity and electrical insulation. When dispensed, Sauereisen cements exhibit the... [Pg.157]
