Photosensitive Materials for PWBs
RY Series for PKG Board
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.
- 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.
