Quanta Computer has reportedly landed orders for Apple's rumored large-size iPad for mass production in the second half of 2014, while Inventec, Quanta and Foxconn Electronics (Hon Hai Precision Industry) are currently competing over Apple's iWatch orders, according to sources from the upstream supply chain.

　　Quanta, Inventec and Foxconn have declined to comment about their orders.

　　Apple has been separating its orders among multiple ODMs recently and has given some of its iPad and iPhone orders to Compal Communications and Wistron, respectively. Apple is also rumored be planning to release a 12.9-inch iPad in 2014 with Quanta in charge of manufacturing the device, the sources noted.

　　Quanta is expected to encounter several challenges in terms of industrial design and assembly when making the large-size iPad. And since the size is not the mainstream specification, order volumes are expected to be limited, the sources said.

　　The sources pointed out that Apple's large-size iPad will mainly target the education and enterprise markets.

　　As for the iWatch, component makers have already started the pilot production, but because of low yields, mass production is rumored to have been postponed from the first quarter of 2014 to the second. In addition to Inventec, Quanta and Foxconn have reportedly been invited by Apple to become manufacturing partners. However, their order proportions have not yet been decided.
