摘要： A suspension comprises a flexure and a plurality of electrical traces. The flexure has a leading portion and a tailing portion, and has a laminated structure comprising a substrate layer, a dielectric layer, and a grounding layer sandwiched therebetween. The electrical traces comprise at least one pair of write traces, each write trace has a bonding pad positioned on the leading portion, a terminal pad positioned on the tailing portion, and a write wire connecting the bonding pad and the terminal pad, the write wire has at least one portion being furcated into at least two sub wires. The present invention can lower the impedance and decrease the signal transmission loss, and widen the frequency bandwidth simultaneously. The invention also discloses a HGA and a disk drive unit.
摘要翻译： 悬架包括弯曲部和多个电迹线。 弯曲部具有引导部和拖尾部，并且具有包括基板层，电介质层和夹在其间的接地层的层叠结构。 电迹线包括至少一对写入迹线，每个写入迹线具有位于引导部分上的接合焊盘，位于尾部上的端子焊盘以及连接焊盘和端子焊盘的写入线，写入线 具有至少一个部分分成至少两个子电线。 本发明可以降低阻抗并降低信号传输损耗，同时扩大频带宽度。 本发明还公开了一种HGA和盘驱动单元。
