Apple is so concerned about the iPhone 8 hitting shelves on time that it has bought kit that produces the phone’s complex circuit boards and leased it to manufacturing partners.
Usually Apple strikes deals with manufacturers and lets them get on with the process of producing parts and assembling the final product.

However, issues with the circuit board for the iPhone 8 have apparently put such a squeeze on production schedules that one Taiwanese partner has pulled out of its deal with Apple.
Now, according to supply-chain sources, Tim Cook and co have stepped in and bought the required equipment for a pair of Korean firms tasked with making the central component that will keep the iPhone 8 ticking.
It’s an unprecedented move and one which shows just how desperate Apple is not to miss the deadline for its tenth anniversary iPhone.
A slew of reports have suggested the phone may not land on shelves until as late as November.
The iPhone 8 is said to feature a new, bezel–free design, OLED screen and vertical dual lens camera.
A launch event is likely to take place in early September.
