Product Overview

As electronic devices become smaller and lighter, the number of sidelight-type backlight boards is increasing. Furthermore, in order to increase the luminous efficiency of LEDs, the surface layers of backlight boards are required to be high in reflectance. Generally, white ink or the like is used, but backlight boards with higher reflectance can be created by adopting the SF-PC®1000-NR.


  • High reflectance (92 to 95% @550nm)

    The reflectance is improved by 10% or more in comparison to white ink coverlay.
  • Capable of reflowing

    Offers high heat resistance, by which the reflectance does not drop even after reflowing.
