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 then conventional films.
Features
- RD-3000 series have excellent adhesion and resolution, make it suitable for fine pattern manufacturing by plating.
- 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.
