DigiTimes is today reporting that the supply chain for the iPhone 5 and iPad 3 is beginning to prepare materials for production of the two devices. According to DigiTimes’ sources, both devices are expected to make their debuts in September and launch to the market in October.

According to the sources, production of both the iPhone 5 and iPad 3 will begin in August with volume starting to pick up in September and October as they launch. The sources also note that roughly 6-7 million units of the iPhone 5 will be produced in the third quarter, in addition to continued production of the iPhone 4.

Upstream component makers including Foxconn Electronics (Hon Hai Precision Industry), which is in charge of assembling the devices; Simplo Technologies and Dynapack International Technology, in charge of manufacturing batteries; TPK Holding and Wintek, in charge of touch panel modules; Catcher, in charge of chassis; and Largan Precision, in charge of webcams, are all expected to benefit from the orders.

Whilst this report affirms previous rumors and analyst expectations of an imminent start of iPhone 5 production, this reports claim of an iPad 3 in October is somewhat questionable. DigiTimes has somewhat of a hit-and-miss record of Apple related rumors, although it should be pointed out that the timeline of an iPad 3 release date is a bit murky. Earlier this year there were rumors of two iPad releases this year, but then more recently DigiTimes itself claimed Apple is beginning their component certification process with a 2012 release time frame for the iPad 3.
