As the official launch of Apple's first-ever foldable smartphone, the iPhone Duo, draws near—with just a little over a month to go—its large-scale manufacturing process is still not fully up to speed. Insiders from the industry reveal that the current success rate for fully assembled iPhone Duo units, as put together by Foxconn, stands at just above 60%, indicating a restricted initial production output. Given Apple's stringent quality benchmarks, it might take an additional six months to a year to reach a well-established stage of mass production. Beyond the difficulties in assembly, Samsung Display's OLED panels and components related to the hinge mechanism have also encountered obstacles, including low yield rates and postponed shipments. A research analysis by Mizuho Securities highlights that issues with hinge specifications and screen creasing have hindered the progress of mass production, prompting Apple to carefully weigh its quality standards in order to push forward with comprehensive production.
