| description | To provide a suspension assembly which can stably connect a magnetic head to a wiring member and a disk device having the suspension assembly.SOLUTION: A suspension assembly includes: a support plate; a wiring member that includes a metal plate 46 and a wiring board 48 arranged on the metal plate, and also includes a tip side portion 42a arranged on the support plate, a base end side portion extended to the outside of the support plate and a connection end part provided at an extension end of the base end side portion; a head 17 placed on the wiring member; and a piezoelectric element 50 mounted on the wiring member. The wiring board includes a first insulation layer and a conductive layer laminated on the first insulation layer. The conductive layer includes: a plurality of connection pads including ground pads to which a ground electrode of the piezoelectric element is connected; a plurality of connection terminals which are provided on the connection end part and include ground terminals; and a plurality of wires W including ground wiring WG for connecting the ground pads and the ground terminals.SELECTED DRAWING: Figure 4
【課題】配線部材に対して磁気ヘッドを安定して接合することが可能なサスペンションアッセンブリおよびこれを備えるディスク装置を提供する。【解決手段】実施形態によれば、サスペンションアッセンブリは、支持板と、金属板４６と金属板の上に配置された配線基板４８とを含み、支持板の上に配置された先端側部分４２ａと支持板の外側に延出した基端側部分と基端側部分の延出端に設けられた接続端部とを有する配線部材４８と、配線部材に載置されたヘッド１７と、配線部材に実装された圧電素子５０と、を備えている。配線基板は、第１絶縁層と、第１絶縁層に積層された導電層とを有し、導電層は、圧電素子のグランド電極が接続されたグランドパッドを含む複数の接続パッドと、接続端部に設けられ、グランド端子を含む複数の接続端子と、グランドパッドとグランド端子とを繋ぐグランド配線ＷＧを含む複数の配線Ｗと、を有している。【選択図】図４ |
