One of the main reasons caused the low Rolled Throughput Yield(RTY) was the drive eccentricity failure which occurred in hard disk assembly process. 而造成该产品流通合格率低的主要原因之一是发生在硬盘装配过程中的磁盘偏心问题。
After the product was put into mass production, the Rolled Throughput Yield(RTY) was hovering at low levels for a long time, much lower than the design target. 该产品在投入批量生产以后,其流通合格率(RTY&RolledThroughputYield)长时间徘徊在低水平,远低于产品设计目标。
