Riston® Dry Film Resists

Riston® EtchMaster ES-102 : Negative working, aqueous processable dry film photoresist. Specially formulated for print and etch application with acid etching including chemical machining. Fine line capablity with wider processing latitude and reduced sensitivity to off-contact. Wide overall proceesing latitude. Ideally suited for use on thin core laminate and flexible substrates.

Riston® MultiMaster MM100 Series : A "general purpose" dry film for acid and alkaline etch, copper, tin, tin/lead, nickel and gold plating. Riston MultiMaster simplifies the complex task of manufacturing diverse circuit boards by eliminating the need for different films in your production line.

Riston® PlateMaster PM100 Series : Negative working, aqueous processable dry film photoresists. Specifcally designed for pattern plating applications on scrubbed and unscrubbed electroless copper, and most direct plate surfaces. Ecellent plating performance in a wide range of plating solutions. Functional in acid etching and tent and etch applications. Fine line capability with wide exposure latitude, and reduced sensitvity to off-contact. Suitable for some nickel/gold plating applications
