Apple's highly anticipated foldable iPhone is experiencing significant production hurdles, with initial output restricted to only a few hundred units per day. Sources indicate that the company's exceptionally high quality control standards are the main impediment, particularly concerning the surface-mount technology (SMT) process for the device's thin and modular printed circuit boards.
According to supply chain reports, even minor deviations in the SMT layout are leading to component rejections, impacting overall yield rates. While some analysts suggest the device remains on track for a September 2026 reveal alongside the iPhone 18 series, the narrowed window between mass production and retail availability has fueled concerns about potential supply shortages and the possibility of a staggered global launch.
The challenges are reportedly not with the flexible OLED panel or the hinge mechanism, but rather with the precision required for the SMT process in a dual-screen foldable design. Apple is applying its rigorous quality standards, which are leading to a higher rate of component failures than typically seen in standard iPhone production.
