Quality of electrically conductive adhesives is a main component in electronic packaging. It highly influences the total quality of a product containing such a component. With time and usage, adhesives lose some of the qualities. In some cases, changes in the molecule structure for example, can be responsible for this influence on material characteristics. This process is known as aging. It can badly...
Electrical conductivity of electrically conductive adhesives is controlled with three mechanisms. These mechanisms are described — a phonon-electron interaction, a constriction mechanism and a tunnel mechanism. If the phonon-electron and constriction mechanisms dominate; the temperature dependence of resistivity is positive and linear, and the temperature coefficient of resistivity is positive. If...
