Resistance and non-linearity of electrically conductive adhesives aged by thermal, humidity and combined aging

Adhesive joints formed of two types of electrically conductive adhesives have been aged at the higher temperature, higher humidity and a combination of the higher temperature/higher humidity. Correlations between these different types of aging have been calculated for joints resistances and joints nonlinearities. It has been found that correlations are high in the case of ECA #1 and low for ECA #2. In research field, aging is applied to test the expected reactions of the most important material parameters of electrically conductive adhesives. It also helps identifying the total operating life of the tested components.
