Riston® Laser Series Dry Film Photoresist

DuPont began formulating specialized photoresists for Laser Direct Imaging (LDI) over 20 years ago, and continues to lead the industry with its Riston® LaserSeries films. 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® LDI300

For specialty outerlayer plating applications on 355nm direct imaging equipment, exposure productivity and plating latitude enhance throughput and yields.

Riston® LDI500

This high productivity film is fully aqueous, possesses ultra-fast photospeed and is compatible with both acid and alkaline etching.

Riston® LDI7000

Customized for tent and etch processes with 355nm direct imaging equipment, with excellent tenting strength, resolution and adhesion with fast stripping that contributes to higher yield and productivity.

Riston® LDI7200

Designed to combine enhanced adhesion and precise plating with clean and fast stripping to achieve increased productivity.

Riston® LDI 8000

Developed for 405 nm LDI equipment, with fast photospeed (13mJ/cm2~) and excellent resolution with wide exposure latitude. Riston® LDI8000 features good conformity, a vivid printout image and strong tenting with excellent hold time stability.
