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.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
