Lithographic Masks TRIZ Cases
- Partial Plating Mask Structure for Isolated Circuit Boards
A conductive-sheet mask enables selective electroplating on isolated circuit metal members without lead wires, resist films, or plating burns.
- Photosensitive Resin Composition for Stable Sensitivity and Color Development
Using cyclopentanone or anisole instead of toluene helps photosensitive resin maintain sensitivity, color stability, and compliance.
- Photosensitive Resin Composition for Accurate PCB Resist Line Widths
Oxime ester photoinitiator loading helps PCB resist patterns match designed line widths and reduces exposure correction time.
