SUSPENSION BOARD WITH CIRCUIT, PRODUCING METHOD THEREOF, AND POSITIONING METHOD OF SUSPENSION BOARD WITH CIRCUIT

摘要

A suspension board with circuit includes a metal supporting board, a conductive layer laminated on the metal supporting board, and a via layer interposed between the metal supporting board and the conductive layer. The conductive layer includes a conductive pattern, and a reference portion serving as a positioning reference for placing the suspension board with circuit on a load beam.

1. A suspension board with circuit in combination with a load beam having at least one through hole configured to receive a pin, the suspension board with circuit comprising:
a metal supporting board; a conductive layer laminated on the metal supporting board; a via layer interposed between the metal supporting board and the conductive layer; and a reinforcing layer made of a metal material, wherein the conductive layer includes a conductive pattern, and a positioning reference hole which is a positioning reference configured to position the suspension board with circuit on the pin on condition that the pin is inserted in the at least one through hole of the load beam thereby to mount the suspension board with circuit to the load beam, wherein the positioning reference hole extends through the conductive layer in a thickness direction, wherein the conductive layer comprises a terminal, wherein the positioning reference hole is formed at a position different from that of the terminal, and wherein the reinforcing layer is formed on a surface of the conductive layer forming the positioning reference hole.
