Abstract
According to one embodiment, an electronic device includes a flexible printed wiring board includes an insulating layer, a plurality of connection pads provided on one side of the insulating layer and constituting a group, and a pad provided on another surface side of the insulating layer and having heat conductivity, wherein the pad overlaps one or more connection pads positioned at an outer edge of the group of connection pads via the insulating layer and comprises a portion extending on the outside of the connection pad on the outer edge, and a connection member includes a plurality of connection terminals connected to the connection pads via a solder.
Claims7
An electronic device, comprising:
- an actuator assembly comprising an actuator block with a side surface, and a suspension assembly extending from the actuator block, the suspension assembly comprising a support plate, a wiring member on the support plate, including an end portion and a connection end portion with a plurality of connection terminals, and a head provided on the end portion of the wiring member;
- and
- a flexible printed wiring board comprising a bonding portion provided on the side surface of the actuator block, the flexible printed wiring board comprising an insulating layer, a plurality of connection pads provided on one side of the insulating layer at the bonding portion and constituting a group, a pad provided on another surface side of the insulating layer at the bonding portion and having heat conductivity, and a second insulating layer covering the pad and the another surface side of the insulating layer, wherein the pad overlaps one or more connection pads positioned at an outer edge of the group of connection pads via the insulating layer and comprises a portion extending on the outside of the connection pad on the outer edge,
- wherein the second insulating layer of the bonding portion is on the side surface of the actuator block, the connection end portion of the wiring member is placed on the bonding portion to overlap the connection pads, and the connection terminals are connected to the connection pads via first solder.
