Abstract
Conductor film terminals of a thin film magnetic head are composed of an Au film while lead terminals of a flexible printed circuit board are covered with an Au layer, so that both of these terminals can be bonded by low temperature ultrasonic bonding directly between Au and Au. The reverse surface of the lead terminals of the flexible printed circuit board is bonded and fixed to a flexible polymer resin cover film so that the dimensional accuracy of the bonded terminal portion can be improved.
