2 UEW / 155 0.03mm PU Copper Wire Ultra Fine Enameled Copper Wire
For Watch / Touch Screen
We are one of the pioneers in producing ultra-fine enameled wires
below 0.03mm in China. Our R & D team has 20 years of
marketexperience.We have achieved the goal of "zero pinholes after
stretching" for ten years. In 2019, our finest diameter is
0.011mm,and mass production has been achieved.When the displays
return the transformer industry, we are the No.1 Chinese brand with
ashare of cake.We rival the internationally renowned enameled wire
brands for production, technology, raw materialsWe surpass them in
terms of "service, quick response"; 30% lower "price" is our
advantage. More and more well-known customers choose us as
suppliers-Philips, Bosch, Panasonic, Samsung ...
