Link to Dow Photoposit SN 68H PhotoPhotoposit SN 68H Photoresist, developed to address industry demands for a robust, high-yielding, fine-line, low-cost photoresist that can be utilized in today’s manual and automatic exposure equipment at optimum productivity levels. Photoposit SN 68H Photoresist has been optimized for use on double-sided roller coaters and is supplied at a viscosity appropriate for roller coating.
The dried resist film is stackable, has a fast photospeed and has the desired flexibility and durability to allow for easy handling. Photoposit SN 68H Photoresist is most sensitive in the 365 nm region. The resist is developed in convectional conveyorized spray equipment using REsolve Developer 9033. It is compatible with conventional acid etchants and is easily stripped with SURFACEstrip 448 Resist Stripper.
