Fabricators are facing ever increasing demands such as decreasing turn-around time, tighter tolerances on registration and imaging on no planar surfaces. Laser direct imaging is a means to resolving these issues. To fully utilize a laser direct imager and minimize operating costs, the photoresist must have ultra fast photospeed but be compatible with all conventional printed circuit board processes.
DuPont began formulating laser direct imaging resists over 20 years ago and has continued to be the leader with the Riston® Laser Series. Laser Direct Imaging (LDI) is moving to the forefront for PWB manufacture based upon its improved registration capability and quick turn capability.
Riston® LDI500 is fully aqueous, possesses ultra-fast photospeed and is compatible with both acid and alkaline etching, as well as copper and nickel/gold plating.
Riston® LDI 800 is specially formulated for 405nm imaging, and features:
- Excellent resolution
- Wide latitude
- Higher productivity
