Carbon Nanotube Composites for Electronic Packaging Applications: A Review

Abstract

Composite engineering comprises of metal matrix composites. They have high strength-weight ratio, better stiffness, economical production, and ease of availability of raw materials. The discovery of carbon nanotubes has opened new possibilities to face challenges better. Carbon Nanotubes are known for their high mechanical strength, excellent thermal and electrical properties. Recent research has made progress in fabricating carbon nanotube metal matrix and polymer-based composites. The methods of fabrication of these composites, their properties and possible applications restricted to the field of electronic packaging have been discussed in this paper. Experimental and theoretical calculations have shown improved mechanical and physical properties like tensile stress, toughness, and improved electrical and thermal properties. They have also demonstrated the ease of production of the composites and their adaptability as one can tailor their properties as per the requirement. This paper reviews work reported on fabricating and characterizing carbon- nanotube-based metal matrix and polymer composites. The focus of this paper is mainly to review the importance of these composites in the field of electronics packaging.

Carbon Nanotubes as Reinforcing Nanomaterials for Rubbers Used in Electronics

“…With the current transition from CB to CNTs due to superior properties and performances of the latter relative to the former, literature has reported that rubber-CNTs composites are currently the major application area for CNTs in the reinforcement of rubbers. Since rubber materials for electronic components need to be precisely shaped to provide proper insulation, electric shock absorption, chemical and thermal resistance and high mechanical strength, and yet be easy to use in the manufacturing and installation of the end product, several researchers have reported that CNTs are the future reinforcing materials for rubbers used in electronics, in partial or complete replacement of conventional fillers, due to the fact that rubber compounds containing CNTs have relatively ultralight weight, extremely high flexibility, and superior chemical, thermal and mechanical properties [6,8,35,49,102]. Owing to their extremely large surface area, CNTs are expected to enhance the matrices of the electronics rubbers and thereby enhancing their poor properties and further improving their good properties to produce rubber-CNTs composite materials with excellent properties [8,34,36,49].…”

Transient Liquid Phase Bonding of Copper Using Sn Coated Cu MWCNT Composite Powders for Power Electronics

“…Carbon nanotubes (CNT) [single-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT)] composites are effective in enhancing the electrical, thermal, and mechanical properties of metals and hence exist as potential candidates in electronic packaging [11][12][13][14]. CNTs are used in electrically conductive epoxy resins [12].…”

Corrosion behaviour of cast and deformed copper-carbon nanotube composite wires in chloride media

“…Since the discovery of carbon nanotubes (CNTs) in 1991 by Sumio Iijima, there has been significant research interest in producing, characterizing and applying their extraordinary properties in practical applications. One of the most researched applications of CNTs is in the formation of composites with existing materials, to provide improved material solutions that meet the ever increasing demands of technology (Bakshi et al, 2010;Aryasomayajula & Wolter, 2013). Copper (Cu) has been traditionally utilized as a conductor material in a plethora of applications, ranging from the very minute microchips of ultralarge-scale integrated (ULSI) devices to electrical wirings and along with aluminium, in massive structures for power transmission in overhead lines.…”
