One Step Closer to the Transparent Electronics
（Heat Resistant Transparent Flexible Copper Laminates）
Previously, typical flexible circuits had no transparency, because of the color of the polyimide films. However, there have been several new transparent and heat-resistant films developed separately, and their copper laminates have become available without adhesives. They can be processed by standard photo-lithography/etching process. The new laminates will open the doors for the transparent electronics.
