Problems solved by technology

Therefore, it is necessary to arrange the head-side terminals and the actuator-side terminals at a high density, and there is a disadvantage that a short circuit easily occurs between the above-mentioned head-side terminals and the driver-side terminals.
[0005] On the other hand, in order to prevent a short circuit, it is necessary to ensure a large space for arranging the head-side terminal and the actuator terminal. However, in this case, it is impossible to compactly mount the suspension board with circuit on the hard disk. Bad condition on the drive

Abstract

A suspension board with circuit includes a conductive pattern, a board main body portion on which a magnetic head is mounted, and an auxiliary portion capable of being folded back with respect to the board main body portion so as to face a back surface of the board main body portion. The conductive pattern includes a first conductive pattern including a first terminal electrically connected to an external circuit, and a second terminal electrically connected to the magnetic head, and a second conductive pattern including a third terminal electrically connected to the external circuit, and a fourth terminal electrically connected to an electronic element. Both of the first terminal and the second terminal are disposed on the board main body portion. The third terminal is disposed on the board main body portion or on the auxiliary portion, and the fourth terminal is disposed on the auxiliary portion.

Description

technical field [0001] The present invention relates to a suspension board with circuit and a manufacturing method thereof, in particular to a suspension board with circuit for a hard disk drive and a manufacturing method thereof. Background technique [0002] Conventionally, it is known to use a suspension board with circuit for a hard disk drive. Such a suspension board with circuit includes a suspension and a conductor pattern formed on the suspension and having a head-side terminal portion for connection to a magnetic head. Furthermore, in this suspension board with circuit, the magnetic head is mounted on the suspension, and the magnetic head is connected to the magnetic head side terminal portion. [0003] In recent years, in order to accurately adjust the position and angle of the magnetic head, it has been proposed to set a micro actuator (micro actuator) around the magnetic head on the suspension (surface) (for example, refer to Japanese Patent Application Laid-Ope...
