Have You Ever Seen A Precision Inductor Coil with A Wire Diameter 10 Times Thinner Than A Human Hair Or Even Finer?

Have you ever seen a precision inductor coil with a wire diameter 10 times thinner than a human hair or even finer? 

Do you wonder what kind of company can produce inductor coils as small as 1mm and assemble components? Do you want to know about the company that owns world-independent winding technology and uses the thinnest enameled wire in the industry at 0.011mm? Read through my article and let me introduce you to a giant in China's coil industry – Dongguan Golden Eagle Electronics Co., Ltd.

When I first joined the company, lacking product knowledge, the department supervisor assigned me to the production line to gain understanding. The first time I went to the production line, I was astonished to see employees manufacturing precision inductor coils. "My god, how is this produced? It's so tiny," I marveled. Driven by curiosity, I went to the workshop to learn about coil winding. From the technicians, I discovered that the wire diameter used for precision inductors is actually 10 times thinner than a human hair, and some are even thinner. What concept is that? A micro-acoustic inductor is made with a wire diameter of 0.011mm to produce products about 1-3mm in size. I used to think centimeters were enough to describe small things, but our wire diameter reaches 0.011mm – it's incredibly precise and amazing.

It turns out that precision inductor coils are used in hearing aids, Bluetooth headsets, sound amplifiers, medical devices, high-end headphones, and various acoustic fields. Making these precise coils is extremely difficult, and many companies are reluctant to produce them due to the complexity. However, our company specializes in researching and developing high-difficulty precision coils. If multiple factories fail to make samples consecutively, they can only try Golden Eagle's factory. There are no more than 4 domestic factories capable of welding precision inductors under a microscope, and we are one of them. Our φ0.5~1mm inductor coils meet the requirements of medical-grade sensors, a precision manufacturing capability that most factories lack.

This is Dongguan Golden Eagle Electronics Co., Ltd., capable of producing precision inductor coils with a wire diameter 10 times thinner than a human hair or even finer.
