Silver Conductive Adhesive Paste: Descriptions, Electrical Usage and Applications

Conductive adhesive paste is the glue form of conductive adhesive, and more advantageous than soldering processes. Since it is more flexible than solder, it is able to cope with vibrations better, and its curing temperature is below the soldering temperature which is important when soldering temperature can be harmful for substrates, so conductive adhesive paste is excellent way for electrical connections on temperature-sensitive substrates, and components. Silver conductive adhesive paste is the most conductive one in conductive adhesives, and circuit resistivity 8.0x10-6Ω cm for highly conductive paste. Therefore, it is commonly used in applications in which low electrical resistance needed.

Although it is expensive for use in solar panels, low resistivity prevent loss of power, so it increase the effectivity. In terms of strength, silver conductive adhesive paste increase the lifetime of solar cells, so that makes it crucial for reliability of solar panels since manufacturers want to provide 25-year warranties. As an applications, in order to reduce the power loss to minimum in dye-sensitized solar cell caused by increase of battery resistance while it is charging, silver conductive adhesive paste have been used for current collection wiring of transparent conductive glass substrate. To support this application, a group tested the silver adhesive conductive paste with conventional sintering type in the table below.

Low resistivity, and mechanical properties of silver conductive adhesive paste allow it to construct many different connection construction. In addition, they can be used for surface mount to replace solder pastes, since they are low in weight and requires less volume than thin solders. For example, in a case study, to construct Z-axis interconnecting for a flip-chip plastic ball grid array package with a 150 µm die pad pitch, they used a silver filled conductive adhesive, they concluded that it maintained strength after 1000 cycle of thermal cycling from -55° C to 120°C.
Despite the fact that silver conductive adhesive paste is expensive to make ordinary connections, low resistivity, flexibility, low curing temperature, form an exclusive access to efficiency and effectivity. As a result, it is necessary for research which electrical qualities considered.

Cadmium Sulfide Nanopowder and Its Applications

Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. As a compound that is easy to isolate and purify, cadmium sulfide the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Cadmium Sulfide Nano Powder, CdS (99.9+%, 20 nm)  shows unique physical, chemical and structural properties from the bulk. The melting point, electronic absorption spectra, band gap energy crystal structure, and other properties of cadmium sulfide nanoparticles are affected by size. Thus, cadmium sulfide on the whole is an attractive system for practicing synthetic chemistry for nanocrystals and for understanding the chemistry, growth history of nanomaterials and also for various technical applications.

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
