Suitable for smartphones, tablets, smart watches, wireless earphones and other mobile terminals/ wearables, with core advantages of ultra-thin and lightweight design, low power consumption, high response speed and strong anti-interference. It supports multiple high-speed communication protocols (5G/4G/Wi-Fi 6/Bluetooth 5.3) to ensure stable signal transmission and reception; the circuit structure is compact, adapting to the narrow internal space of foldable/portable devices, and works stably in the temperature range of -20℃~70℃, meeting the daily use and long-term reliability requirements of consumers.
Adopt high-frequency low-loss multi-layer PCB (high-Tg FR-4) and flexible PCB (FPC) to realize compact wiring of foldable mobile phones and wireless earphones, reducing product volume by 30%%; use low-power power management chips to extend battery life of wearables (smart watch standby ≥7 days, earphone usage ≥6 hours); optimize antenna matching circuit design to improve signal receiving sensitivity (increase by 25-35%) and reduce signal interference; use precision surface mount technology (SMT) to improve component density and welding reliability, and adopt anti-oxidation gold-plated process to extend service life of connectors.
Flagship smartphones use high-stability circuit layout to support 5G+Wi-Fi 6 concurrent connection, realize 1Gbps high-speed download, and ensure smooth operation of multi-tasking/AI functions; wireless earphones adopt low-power communication circuits to achieve ultra-low latency (≤20ms) audio transmission, and adapt to long-term wearing with small size; smart watches integrate multi-sensor (heart rate, blood oxygen, motion) signal acquisition and processing circuits, with stable data transmission and long battery life; foldable mobile phones use flexible FPC wiring to support 100,000+ folding cycles, without circuit damage or signal interruption.
Miniaturized and high-density circuit processing increases production difficulty, and the yield of complex flexible circuits is about 87-89%; consumer terminals face frequent hardware/software upgrades, requiring circuits to have good scalability, increasing design complexity; there is a contradiction between product appearance (thin/light) and signal/heat dissipation performance, which is difficult to balance; low-cost market has serious homogenization, and core components (chips, sensors) are highly dependent on imports, limiting product innovation.
