Riston® 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.

DUPONT PRODUCTS & SERVICES

  • Riston® FX Dry Film Photoresist

    DuPont has developed the Riston® FX Series of photoresists to help fabricators address challenges of producing fine lines at high yields.

  • Riston® EtchMaster Series Dry Film Photoresist

    Riston® EtchMaster dry film photoresist is specifically designed as an acid etching film that delivers high yields in fine line applications. These photoresists provide excellent conformation using dry lamination and possess wide exposure, developing and stripping latitude.

  • Riston® GoldMaster Series Dry Film Photoresist

    Riston® GoldMaster is a fully aqueous resist that simplifies circuit board fabrication with special gold plating or nickel plating finishes

  • Riston® MultiMaster Series Dry Film Photoresist

    DuPont™ Riston® MultiMaster Series simplifies the manufacturing operation by eliminating the need for different films in your production line.

  • Riston® PlateMaster Series Dry Film Photoresist

    Riston® PlateMaster was formulated to achieve consistently high yields by providing outstanding plated line uniformity, fine line resolution, and wide surface tolerance on direct metallization and panel plate.

  • Riston® TentMaster Series Dry Film Photoresist

    DuPont™ Riston® TentMaster provides excellent tenting capability, outstanding conformation, excellent resolution and remarkable tolerance to off-contact exposure.

  • Riston® Laser Series Dry Film Photoresist

    Ultra fast photospeed, high performance, and compatibility with conventional printed wiring board (PWB) processes are critical to help PWB fabricators optimize their LDI equipment investments.
