Ultra-Thin & Automotive Grade Coils from Dongguan Golden Eagle

Dongguan Golden Eagle Electronics Co., Ltd is a professional Chinese manufacturer specializing in the R&D and mass production of high-precision wireless charging coils. With over 20 years of manufacturing experience, we focus on customized ultra-thin wireless charging coil and car wireless charging coil solutions. As a reliable custom wireless charging coil supplier, we serve global clients in wearable devices, consumer electronics, automotive electronics and smart home industries. All products comply with ISO9001 and IATF16949 standards, supporting flexible OEM and ODM customization.

We excel in ultra-thin and high-precision wireless charging coil manufacturing. Our self-developed custom wireless charging coil reaches an ultra-slim thickness of 1.35mm, perfectly solving structural limitations of miniaturized electronic products. Compared with ordinary wireless charging coils on the market, our products feature lower power loss, higher charging efficiency, strong anti-interference performance and stable batch consistency, ideal for high-end precision equipment.

A renowned European wearable brand launched a new ultra-thin smartwatch project with an integrated slim body design, leaving very limited internal installation space. The client required a customized ultra-thin wireless charging coil within 1.35mm thickness, supporting stable 5W constant-power charging with strict inductance tolerance, to ensure consistent user experience. The coils also needed to pass multiple reliability tests for daily complex usage scenarios.

Most conventional wireless charging coil manufacturers failed to balance ultra-thin size and stable performance, resulting in unstable charging, excessive heat and low yield. These technical bottlenecks delayed the client’s new product launch. To solve this problem, the R&D team ofDongguan Golden Eagle Electronics Co., Ltd optimized the winding structure, wire arrangement and magnetic sheet matching scheme for the ultra-thin wireless charging coil, and calibrated core parameters for stable performance.

We completed prototyping and full performance testing within 3 working days. Our customized ultra-thin wireless charging coil samples successfully passed all reliability tests, including high-low temperature resistance, drop test and long-term aging test. The products effectively solved industry pain points such as unstable charging and overheating of ultra-thin wearables. After trial production verification, we officially started mass production. At present, we maintain a stable monthly output of 300,000 pieces with a yield rate over 99.8%. We have achieved zero defects and zero after-sales complaints for two consecutive years, becoming the exclusive long-term custom wireless charging coil supplier for this European brand.

Besides wearable ultra-thin wireless charging coils, our flagship car wireless charging coil is widely used in automotive central control charging modules. This high-performance wireless charging coil features excellent anti-interference ability, strong adaptability to complex vehicle power environments and long-term stable operation, fully meeting automotive-grade quality requirements.
