IC yield issues shroud iPhone 5S manufacturing
Apple may not be able to ship iPhone 5S in huge numbers soon after its rumoured launch in September as latest reports indicate that the manufacturing of the iPhone 5 successor may be delayed because of poor yields of fingerprint-recognition chips and LCD driver ICs.
There have been reports of Apple including a fingerprint sensor in the next iPhone as early as March this year following which it was claimed that iPhone 6 which will have the sensor and not the iPhone 5S. Digitimes has it from its sources that because of yield rates related to the fingerprint-recognition chips and LCD driver IC the commercial production of the chips, which should have started back in June or early July, will commence by late July which will put pressure on the supply of the handsets.
The issues are present because of problems with the original design of the fingerprint-recognition chip. The report claims that a total of 3 million units of iPhone 5S will be delayed to the fourth quarter which may lead to delays in shipment of the next-iPhone during the third quarter.
