iPhone 17 Pro Max to Feature Thinner Circuit Boards with RCC for Extended Battery Life
Originally Published 2 years ago — by MacRumors
iPhones are not expected to adopt resin coated copper (RCC) foil for their circuit boards until 2025, according to Apple analyst Ming-Chi Kuo. The delay is due to concerns over the material's fragility and inability to pass drop tests. If improvements are made by Apple's supplier Ajinomoto, the high-end iPhone 17 models could potentially use RCC in 2024. RCC has the potential to slim down circuit boards, creating more space for larger batteries or other technology, and simplifies the manufacturing process.
