Abstract
A flexible circuit board, an end of which is uniformly connected to the inside of a springy metal layer, which has been bent to a U shape, and the rest of which extends in a predetermined width away from the springy metal layer. The flexible circuit board is equipped with bump-shaped connecting terminals on the opposed bent sections, each connecting terminal having a first side connected to the ends of the circuit wiring pattern formed on the flexible circuit board and a second generally opposed side projecting outwardly from the flexible circuit board. The bump-shaped terminals are electrically connected to the terminal of the magnetic head suspension, which is made integral with circuit wiring, by the clamping force of the springy metal layer.
Claims3
A magnetic head junction board for electrically connecting a magnetic head suspension and a read/write amplifier substrate, said board comprising:
- a flexible circuit board, the ends said board being uniformly connected to the inside of a springy metal layer, which has been bent to a U shape having a predetermined width, and the rest of said board extending in a predetermined width away from said springy metal layer;
- said flexible circuit board is equipped with connecting terminals on the opposed bent sections, each connecting terminal having a first side connected to the end of a circuit wiring pattern formed on said flexible circuit board and a second generally opposed side projecting outwardly from said flexible circuit board;
- and
- said connecting terminals are electrically connected to associated terminals of the magnetic head suspension whereby electrical circuitry of the magnetic head suspension is integrated with said circuit wiring pattern by a clamping force provided by said springy metal layer.
