Recent advances in electrically conductive adhesives for electronics applications

As a potential alternative to lead-bearing soldering technology, conductive adhesive technology has attracted more and more attention from the electronics industry. This new technology can offer numerous advantages over traditional soldering technology. However, some critical limitations of this technology has slowed its potentially wide applications in the electronics industry. These limitations include lower electrical conductivity, increased contact resistance during elevated temperature and humidity aging, and poor impact performance. In the past few years, there has been tremendous efforts in addressing these issues, and conductive adhesive technology has advanced significantly. This paper will give an overview of the main research work and achievements in conductive adhesive technology.
