摘要:
An actuator structure includes a flexure suspension with a flag appendage having a cantilevered portion extending parallel to the arm-suspension to form a gap therebetween. The flex cable that connects to the device electronics has an elongated portion secured to the side of the arm-suspension assembly presenting termination pads, which extend to the cable edge, along the elongated portion side and in alignment with the gap between arm-suspension and flag. The leads extending from the transducer are fanned out and extend across the gap. The leads are bonded to the arm-suspension and to the lead cantilevered portion immediately adjoining the gap. To terminate the leads, the flag is folded down 90 degrees, bringing the leads into contact with the termination pads where they are ultrasonically bonded. The flag is then bent toward its original position causing the fine lead wires to separate between the flag cantilever portion bond and the ultrasonically bonded termination. As the flag is bent back, the fragile connections, between flag and flexure, rupture and the flag is separated from the balance of the arm-suspension assembly. In the assembled condition, the bonding of the fanned out lead wires to the arm-suspension provides strain relief.
