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.

Circuit Imaging Materials for PCBs

  • Dry Film Photoresist

    Dry Film Photoresist

    Used in tenting, plating, akaline etching or innerlayer applications.

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

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

    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.

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

    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.

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

    YieldMaster? Technology delivers optimum yields through the use of a specially developed thin resist, lamination system
  • Imagemaster? Diazo Phototool Films

    Imagemaster? Diazo Phototool Films

    For use in exposing liquid and dry film photoresists (including solder masks) employed in the manufacture of PWBs.

  • Screen Printed Inks (CB Series)

    Screen Printed Inks (CB Series)

    The CB Series of screen printed ink materials are used for additive, low temperature processing on both rigid and flexible printed circuit boards (PCBs).
