Reporting today is news that one of the iPhone 5 manufacturers, Wintek, is finding a ‘delayed bubble’  fault in some of the iPhone 5 panels it is producing. The fault appears during assembly, the source claims, and not in a completely assembled unit, generally as these faults are detected during quality analysis. Wintek is reported to be providing around 20-25% of the panels for the iPhone 5 with Apple using several different manufacturers in the manufacturer of parts, components, and final assembly and testing. There is speculation that this may effect the level of units available at launch though Wintek refute this. Generally the panels are quicker to manufacture than other components so there would be a level of fault, resulting in the faulty parts being destroyed, that could be tolerated before having a critical affect on supply. Additionally there is no news whether this just pertains to one batch of parts or all batches since manufacture began. As has been reported in the past, and confirmed by one of Apples largest manufacturers Foxconn, Apple parts can be extremely difficult to make, especially with Apples zero tolerance approach to even the slightest amount of non-specification results. Apple has not commented on this speculation so confirmation can not be guaranteed, and Apple is reported to still be highly confident of shipping over 25 million units at launch. A special event by the tech heavy weight is due on October 4 which is being treated as the official release of the iPhone 5. As of yet a guaranteed Australian release date is waiting to be released.
