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.
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.
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.
