With the anticipated fall unveiling of the iPhone 14 series, Apple has been gearing up to begin mass production in the coming weeks.  

Apple, however, is expanding its list of suppliers for the upcoming iPhone 14 models as the company experiences supply issues. 

On Twitter, Apple analyst Ming-Chi Kuo said that SG Micro's components had been certified as meeting Apple's standards for the 14th generation of iPhones 

The Chinese integrated-circuits specialist joins Apple's roster of manufacturers for the iPhone 14 Pro and iPhone 14 Pro Max. 

This year's iPhones will feature integrated power management circuits from SG Micro, which are responsible for managing the battery and the level shifter.  

Kuo says this marks the first time SG Micro has supplied components for Apple's high-end products, boosting sales for the Chinese firm and increasing demand for the iPhone 14. 

Apple also started working with new camera component suppliers earlier this year in preparation for the iPhone 14 Pro. 

The analyst adds that the partnership with SG Micro suggests the company's chips "have reached the Tier 1 level" of technical sophistication necessary for incorporation into high-end electronic gadgets.
