Wireless Charging Coil for High-End Flagship Smartphones

Dongguan Golden Eagle Electronics Co., Ltd. (GOLDEN EAGLE) has nearly 20 years of experience in precision wireless charging coils, smartphone wireless charging transmitter coils, and Qi standard wireless charging coils, known as a "master of precision in the coil industry". With top-notch manufacturing technology and strict quality control standards, it has obtained the exclusive supply qualification for flagship models of leading global smartphone brands. With an ultra-fine precision winding wireless charging coil with an inner diameter of only 0.19mm, it has set a new precision benchmark for core smartphone wireless charging components.

Nowadays, high-end flagship smartphones focus on camera performance, hardware configuration and ultra-thin body design. However, traditional ordinary wireless charging receiver coils are bulky and low-precision, difficult to fit compact phone internal space, causing slow charging and serious overheating. To solve this industry problem, Golden Eagle developed themini ultra-thin wireless charging coil with an inner diameter of 0.19mm by adopting an independent tension control system and imported fully automatic winding machines, which is unique in the industry.

This mini coil is not only small in size but also high in performance, known as a special wireless charging coil for flagship smartphones. Its volume is 30% smaller than ordinary coils, saving more internal space for ultra-thin body design. The dimensional tolerance is controlled within 0.01mm and inductance tolerance ±2.5%, realizing fast charging, high efficiency and low heat generation. The charging efficiency is increased by 12% and heat reduced by 15%, effectively solving the mobile phone overheating problem during wireless charging.

As a car-grade quality wireless charging coil manufacturer, Golden Eagle implements 75 quality control checkpoints and 100% full inspection for each product. All products have passed IATF16949 and ISO certifications, with long service life and stable performance without deformation or attenuation. At present, the 0.19mm ultra-precision coil has been mass-produced and supplied to leading smartphone brands as a core supporting component.

Golden Eagle specializes in wireless charging coil customization, precision winding processing, and core wireless charging accessories for mobile phones. We insist on technological innovation and precision manufacturing to support global brands to create high-quality wireless charging electronic products.
