Abstract
Abstract An interconnection arrangement for interconnecting a high-current carrying cable with a metal thin-film ( 3, 4 ) on a transparent and insulating substrate ( 1 ). According to the invention the high-current carrying cable is designed as a flat cable ( 5 ) and the inter-connection between the flat cable and the metal thin-film ( 3, 4 ) is an ultrasonic weld joint ( 6 a , 7 a ).
