Abstract:
A method for welding a flexible flat cable to a member, the flat flexible cable having a conductive element covered on opposite first and second sides by an insulation coating, comprising:stripping part of the insulation coatings from the first side of the flexible flat cable for exposing a section of the conductive element; introducing the flexible flat cables and the members between a horn and an anvil of an ultrasonic welding machine so that the exposed section of the conductive element is held substantially in contact with the member, the horn having a press-contact surface with a plurality of elongated projection; pressing the elongated projections into contact with the insulation coating on the second side of the flexible flat cable; and transmitting an ultrasonic vibration to the horns for causing the elongated projections to bite into the insulation coating layer and substantially into contact with the conductive element for ultrasonically welding the conductive element to the member.
