Transparent Glass PCB
Transparent Glass PCB, it used in the LED, 5G, LCD, etc with the 360-degree light-emitting package and transparent glass invisible wire decoration.
The glass substrate has unique advantages in the flatness, transparent, deformation, heat resistance, tear-resistance, etc, the deformation rate is very low under the high temperature working for a long time, the glass PCB can 360-degree luminescence, 80 color rendering index can be 140lmw or more, it doesn’t need to add the heat sink, and there is no light attenuation. Currently, the glass PCB widely used in the LED display, solar, 3D printer, etc
FX PCB developed its own technology on the glass PCB, which can greatly improve the copper thickness and adhesivity on the glass, please see FX PCB capability, and the advantage compared to other glass PCB technology
