Advanced Dry Film Photoresist 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® products meet the industry demands for finer features, higher quality and lower cost in all types of plating and etching applications. DuPont™ Riston® dry film, the first dry film photopolymer photoresist, makes the fabrication of printed circuit boards more productive and more reliable.
