Riston® Dry films

Request a sample

DuPont™ Riston® dry film photoresist revolutionized the way PCBs were fabricated when invented by DuPont 40 years ago. The original dry film photoresist is the industry standard for high yield, productivity, and ease of use in all imaging applications, including the latest industry demands for finer features, higher quality and lower cost in all types of plating and etching applications as well as LDI exposure.
