Isotropic and anisotropic electrically conductive adhesives (ICAs and ACAs) are alternative materials for substitution of common used tin-lead solders in electronic assembly. Electrically conductive adhesives are potential materials for the bonding of surface mounted components and for some special applications. In this research we are focused on an investigation of influence of high current load on changes of quality of adhesive joints. Monitored parameters are electrical resistance and nonlinearity of V-C characteristics. Research is divided into two types of high current load: a) direct current (DC), amplitude 1 A, b) current pulses 1:1, f= 500 Hz, amplitude 1.41 A.
