摘要： A slider for a head gimbal assembly includes a trailing surface, a plurality of connection pads arranged on the trailing surface adapted for both bonding the slider to a suspension of the head gimbal assembly and testing the performance of the slider. At least a part of the connection pads each comprises a bonding portion and a testing portion electrically connected to the bonding portion and larger than the bonding portion, all the bonding portions and the rest part of the connection pads are arranged in a first row and the testing portions are arranged outside the first row. The slider of the present invention has a new pad layout to facilitate bonding of the connection pads and permit to provide additional pads thereon to connect the additional sensors therein for precise reading and writing, thereby improving the performance of the slider. The invention also discloses a head gimbal assembly and a disk drive unit including the same.

摘要： A common tray for HGA comprises a frame, a first inner bar, and a second inner bar parallel to and spaced from the first inner bar. Ends of the first and second inner bars connect to the opposite edges of the frame. A plurality of locating pillars and a plurality pairs of first bumps are uniformly-spaced formed on the first inner bar respectively. The first inner bar has portions between each said pair of first bumps recessed for forming spaces under the HGA. A plurality of second bumps are uniformly-spaced formed on the second inner bar for withstanding an edge of the base plate. The present common tray can replace five kinds of trays traditionally used in the HGA manufacturing process, and thus reduce the load/unload operations as well as the no-value stations and operators, thereby the productive efficiency is improved, and manufacturing cost is reduced.
摘要翻译：用于HGA的常见托盘包括平行于并与第一内杆间隔开的框架，第一内杆和第二内杆。第一和第二内部杆的端部连接到框架的相对边缘。多个定位柱和多对第一凸起分别形成在第一内杆上均匀间隔开。第一内杆在每个所述一对第一凸块之间具有凹部，用于在HGA下形成空间。多个第二凸起均匀间隔地形成在第二内杆上，用于承受基板的边缘。目前的通用托盘可以代替传统上在HGA制造过程中使用的五种托盘，从而减少了载荷/卸载操作以及无价值站和操作者，从而提高了生产效率，降低了制造成本。
