Resist Details TRIZ Cases
- Wiring Circuit Board Nickel Layers for Corrosion Protection
A low-phosphorus nickel layer protects circuit-board wires while selective coating removal helps maintain production efficiency.
- Wiring Circuit Board Assembly Sheet Margin Region Turbulence Control
A wiring circuit board assembly sheet uses a dummy pattern in the margin region to stabilize etching solution flow.
- Wired Circuit Board Inclined Face Light Reflection Control
An inclined insulating face directs reflected exposure light away from photoresist areas to maintain conductive pattern geometry during lithography.
- Etching Method Using Inkjet Resist for Precision Corrosion Control
Inkjet printing forms a resist layer using monofunctional and polyfunctional oligomers to define etching patterns on target surfaces.
