Report says that Apple is replacing Samsung with Unimicron to produce Ax chips30
You know that Apple wouldn't let Unimicron make important parts for its most important devices without passing a test. As a result, the company did produce, on a smaller scale, the basic ARM foundation for Apple's processor known as the "chip scale package". According to China Times, Unimicron will increase production for Apple once its new production facility is opened.
Apple is also giving TSMC the assignment of producing some of its Ax chips. Ther Ax processors are currently made by Samsung at a factory in Austin that Samsung is expanding. In the meantime, Apple has moved away from obtaining batteries and panels for the Apple iPad from Samsung.
