PCB solder mask exposure LDI exposure machine

Rigid PCB Equipment

1）Past photo film problems have led to imperfect images because they are vulnerable to temperature or humidity fluctuations.Laser images can produce more accurate and consistent images and eliminate any film related defects.
2）Laser imaging provides precise positioning and improved resolution.Image lines, space and alignment are more accurate.
3）The film method requires a temperature and humidity controlled environment in order to provide the most accurate image transmission for the image. LDI reduces the influence of the environment on the resulting image and eliminates the influence of light refraction inherent in photo processing technology.
4）LDI exposure machine is easier to realize automatic operation, saves labor cost, greatly improves product quality and avoids defective rate.
