Dry Film Photoresist


Riston® Dry Film Photoresists for Denser More Complex Boards

DuPont™ Riston® dry film photoresist revolutionized the way printed circuit boards were fabricated when it was invented by DuPont 40 years ago.

The original dry film photoresist invented by DuPont is the industry standard for high yield, productivity, and ease of use in all imaging applications. DuPont™ Riston® products meet the industry demands for finer features, higher quality and lower cost in all types of plating and etching applications.
