Photosensitive Dry Film "PHOTEC"RD Series for Direct Imaging

Image of RD Series for Direct Imaging

RD series are fully aqueous applicable photosensitive films used for direct imaging system. These series have high photosensitivity, high resolution, excellent imaging property and other advantages than conventional films.

Features

  • RD-2015 has high photosensitivity and excellent tenting reliability for small diameter holes.
  • RD-1225 is suitable for semi-additive process with high resolution and excellent stripping property.
  • It is used for digital light processing (DLP) system and UV laser direct imaging (UV-LDI) system both.
  • Because of high imaging property, it is able to confirm the exposed area.
