Frequency Dependence of Impedance of Adhesive Joints [PDF]

, 2006
Electrically conductive adhesives have, in comparison with solders, significantly higher non-homogeneity of the structure, and therefore stability of electrical as well as mechanical properties of adhesive joints is lower than soldered ones.
