“Electrical Conductive Adhesives with Nanotechnologies” begins with an overview of electronic packaging and discusses the various adhesives options currently available, including lead-free solder and ECAs (Electrically Conductive Adhesives). The material presented focuses on the three ECA categories specifically, Isotropically Conductive Adhesives (ICAs) Anisotropically Conductive Adhesives/Films (ACA/ACF) and Nonconductive Adhesives/Films (NCA/NCF). Discussing the advantages and limitations of each technique, and how each technique is currently applied. Lastly, a detailed presentation of how nano techniques can be applied to conductive adhesives is discussed, including recent research and development of nano component adhesives/nano component films, their electrical properties, thermal performance, bonding pressure and assembly and reliability.

This book presents a comprehensive overview of nanoscale electronics and systems packaging, and covers nanoscale structures, nanoelectronics packaging, nanowire applications in packaging, and offers a roadmap for future trends. Composite materials are studied for high-k dielectrics, resistors and inductors, electrically conductive adhesives, conductive "inks," underfill fillers, and solder enhancement. The book is intended for industrial and academic researchers, industrial electronics packaging engineers who need to keep abreast of progress in their field, and others with interests in nanotechnology. It surveys the application of nanotechnologies to electronics packaging, as represented by current research across the field.

This book is based on two Special Issues of the Journal of Adhesion Science and Technology (JAST vol. 22, no. 8-9 and vol. 22, no. 14) dedicated to the logic of electrically conductive adhesives. The contains a total of 21 papers (reflecting overviews and original research).

Nanotechnologies are being applied to the biotechnology area, especially in the area of nano material synthesis. Until recently, there has been little research into how to implement nano/bio materials into the device level. “Nano and Bio Electronics Packaging” discusses how nanofabrication techniques can be used to customize packaging for nano devices with applications to biological and biomedical research and products. Covering such topics as nano bio sensing electronics, bio device packaging, NEMs for Bio Devices and much more.

Electrically conductive adhesives (ECAs) have recently become a critical technological area in component development behind solar cell packaging for die attachment, solderless interconnects, and heat dissipation. The standard example of an ECA employs the use of conductive fillers within a polymeric matrix or host to render the final composite conductive. Electrical conductivity of an ECA is governed by percolation theory, wherein the necessary fillers that host electrons transfer, via physical connection or tunneling, must reach some critical volume fraction to accommodate probable conductive pathways that would be large enough to be considered isotropic [1,2]. Many fillers exist for use in this role, but commonly silver is chosen for its high electrical and thermal conductivities [3]. However, silver (especially micro- or nano-structured) remains an expensive commodity, and typical volume fraction loadings in ECA can approach >30%. This is necessary as the theoretical critical volume fraction required for monodisperse spheres in a randomly oriented isotropic system is ~16% [4]. Such excessive filler loading not only invalidates economic feasibility, but also deteriorates mechanical properties inherent for the host polymer. To mitigate the critical percolation threshold (pc) for volume fraction loading of a filler, combative methods are articulated herein. One approach is to use low-dimensional, high-aspect ratio fillers, such as graphene and carbon nanotubes (CNTs), which have been shown to lower pc [5,6]. Typically, such fillers are more expensive than silver; however, given the low-loading implied to achieve a percolated network, this approach could improve the economic feasibility as an added filler for reducing total filler loading required [7]. In this work, commercial CNTs are employed as a high-aspect ratio filler for the reduction of silver filler loading in an ECA system. Graphene nanoplatelets are also synthesized and used to demonstrate a route for creating tailored high-aspect ratio, low-dimensional fillers which are effective at generating a percolated network at relatively low loading. Utilizing a pre-percolated CNT system, a hybrid silver/CNT system was then generated to achieve enhanced conductivity at lower total loading over pure silver systems, which exhibited a conductivity of 54 S/cm at 12 vol.% loading with a CNT loading of only 8 wt.%. 1.
