Circuit Imaging Materials

High Yield Imaging Materials for Printed Circuit Board Fabrication

DuPont has been a leading innovator and global supplier of imaging materials for the printed circuit board (PCB) industry for more than 40 years.

DuPont imaging materials are key in the fabrication of printed circuit boards.  Fabricators challenged to produce denser and more complex boards choose DuPont for improved product and process solutions.  Our portfolio of products is specifically engineered to enable PCB fabricators to easily achieve higher yields and greater productivity, even with today's most challenging designs.

DuPont™ Riston® dry film, the first dry film photopolymer photoresist, makes the fabrication of printed circuit boards more productive and more reliable. Our phototooling films provide the medium for reliable image transfer, and our DuPont™ Vacrel® Dry Film Soldermask protects the circuit board from environmental effects to enhance the life and reliability of the circuits.

Riston® EtchMaster 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® 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® 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® 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.

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.


Imagemaster™ Diazo Phototool Films

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