High-Difficulty Precision Inductance Coil Manufacturer with Microscope Welding Case – Golden Eagle

If you are sourcing a professional precision inductance coil supplier for high-end electronics, Dongguan Fuying Electronics Co., Ltd. (GOLDEN EAGLE) is your best choice.

We have more than 500 sets of imported production equipment, specialized in developing and producing high-difficulty precision inductance coil, custom inductance coil, special shaped coil and wireless charging coil for global customers.

One of our core advantages is precision coil welding under high-magnification microscope.

Many tiny ultra-fine coils cannot be processed by ordinary machines. Our experienced operators complete micro welding under a high-power microscope to ensure stable inductance, perfect soldering points and consistent product performance.

Real Application Case

A well-known consumer electronics brand needed ultra-thin miniature inductance coils for their TWS earbuds.

The product required ultra-fine wire winding and invisible micro welding, which most factories could not achieve.

Less than 4 factories in China can support this strict process standard, and we are one of them.

We customized the coil structure, controlled the tolerance within micron level, and finished all welding work under a high-magnification microscope. After sample testing, mass production was launched smoothly, with stable quality and zero defective rate.

As a reliable wireless charging coil manufacturer, we have ISO9001, UL, CE, RoHS certification and over 20 years of R&D experience.

We provide OEM / ODM service for smart wearables, TWS earbuds, wireless chargers, medical electronics and automotive electronic projects.
