Abstract
This paper deals with reliability of joints glued by non-conductive adhesives (NCA) on flexible substrates during electrical current ageing. Also the comparison of NCA joints ageing with ECA joints ageing is presented in this paper. Two types of adhesives were used for the experiment-non-conductive UV curable acrylic adhesive Loctite AA3926 (NCA) and electrically conductive two part epoxy adhesive MG 8331S (ECA). The purpose of the experiment was to verify the reliability of NCA joints during the electrical current accelerated ageing. The electrical resistance of UV NCA joints on flexible DuPont Pyralux substrate before, during and after electrical current load was better than resistance of ECA joints and UV NCA can be recommended.
