Photosensitive Materials for PWBs
RD Series for Direct Imaging
Product Information and Application
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.
