Rumor has it that, at launch, the iPhone 5S is going to be supplied in limited numbers as poor yield rates of certain components are likely to cause production delays.

iPhone 5S iPhone 5S supplies reportedly constrained at launch

Components related to fingerprint recognition and the iPhone 5S LCD are said to have issues, thus reportedly slowing down yield rates. We’ve heard in countless rumors that iPhone 5S is going to come with a fingerprint sensor. It will primarily be used to lock and unlock the device without the need for entering a pin code. The fingerprint sensor chip is designed by AuthenTec, a company that Apple acquired last year. There presumably are issues with the original design of this chip that have caused lower yield rates. Taiwan Semiconductor Manufacturing Company is believed to be manufacturing these chips.

Just yesterday it was reported that iPhone 5S mass production, in a small batch, will begin later this month. Many analysts have reported that iPhone 5S will essentially be delayed due to the fact that enough units can’t be produced fast enough due to these manufacturing problems. Recently purported specifications of iPhone 5S were posted online, the device is believed to have NFC, fingerprint sensor among various other things.

Apple is expected to unveil the iPhone 5S in September, with the actual launch may take place in October. If supplies are really going to be constrained, it could take quite a while for markets other than the U.S. to get Apple’s latest flagship smartphone.
