HM Series for Thick Resist Layer
Photosensitive Dry Film “PHOTEC”
About the product
HM series are photosensitive films to form a thick resist layer with higher aspect ratio.
They are used for electro-forming such as metal mask.
Features
- Excellent resolution and adhesion make it possible to form a resist with higher aspect ratio.
- Thickness lineup according to the application (thickness; 35～200 µm, available upon request)
- Smooth sidewall of plating line due to the smooth resist profile.
