Initial run may be limited to 3-4 million units
Initial production of the iPhone 5S may reach only 3 to 4 million units in the current quarter, compared an earlier plan for 10 million, industry sources claim. The issue is said to be the phone's fingerprint sensor; while it was reportedly going to start production at TSMC in May, and then head to packaging at Xintec, Apple has allegedly need further work on integrating the part with iOS 7. Xintec, meanwhile, is said to be returning low yields.
Mass production of two parts may only start at end of July
Manufacturing problems are affecting the amount of iPhones Apple will have in time for September's iPhone 5S launch, sources tell DigiTimes. Suppliers are reportedly getting poor yields of fingerprint recognition chips and integrated circuits for LCD drivers. Mass production of both parts was supposed to have started at the end of June or in early July, but is now believed to have been pushed to the end of July, mirroring claims by Jefferies & Co. analyst Peter Misek. If accurate, the sources' claims could be the first confirmation that the 5S uses fingerprint recognition.
