Apple Was Initially Expected to Upgrade PCB Materials in iPhone 16 Models in 2024
Apple was reportedly planning to implement new resin-coated copper (RCC) components in its upcoming iPhone models to achieve a slimmer and more compact design. Initially, these changes were expected to debut with the iPhone 16 lineup in 2024, but they were later postponed to the iPhone 17, anticipated for release in 2025. However, according to well-known Apple analyst Ming-Chi Kuo, the company’s plans to introduce RCC components in its iPhones have been further delayed, primarily due to concerns about durability and fragility.
Delayed Plans for RCC Components in iPhones
In a recent post on X (formerly Twitter), Ming-Chi Kuo revealed that Apple has decided to hold off on using RCC components in its iPhone models. Kuo noted that the company has not yet been able to meet its stringent quality standards with the new material, leading to the decision to delay its introduction in the iPhone 17, expected in 2025. This marks the second time that Apple has postponed the implementation of RCC technology in its devices.
RCC Components and Their Potential Benefits
RCC components were seen as a potential game-changer for Apple, offering the possibility to significantly reduce the size and thickness of the iPhone’s mainboard. By replacing the current copper-clad laminate (CCL) materials with RCC, Apple could potentially create more internal space within the device. This extra space could be used to accommodate larger batteries, thereby enhancing battery life without increasing the overall size of the phone.
Concerns Over Durability
The delay in adopting RCC technology appears to stem from concerns about the durability and fragility of the new material. While RCC could offer significant benefits in terms of design, it may not yet be robust enough to meet Apple’s high standards for reliability and longevity. As a result, the company has decided to take more time to refine the technology before introducing it in its flagship devices.
Initially, Apple was rumoured to upgrade the PCB materials in its iPhone 16 lineup in 2024, but it was then reportedly pushed to the iPhone 17 series. Kuo doesn’t say whether RCC components will be introduced with the iPhone 18 in 2026 or the iPhone 19 in 2027. However, Apple has not revealed any details about switching to RCC materials yet so it’s better to take these latest claims with a grain of salt.
