Photosensitive Materials for PWBs
RY Series for PKG Board
Product Information
RY series are aqueous type photosensitive films used for high density semiconductor package such as BGA, CSP and so forth. RY-5100 series have excellent adhesion and resolution and less resist foot and the other advantage.
Features
- These films are suitable for semi-additive process with high adhesion, high resolution and stable line width.
- Shorter resist foot can contribute to finer pattern manufacturing. Excellent resist profile (smooth resist side wall) results in smooth plating line profile.
