PWD Series – PCB Wet-Chemical R2R Developing
Roll-to-roll (R2R) developers of the PWD Series completely remove dry films, wet films or ink which have not been exposed. Our R2R-developers for the production of FPCs are matched with stripping and etching processes and comprise following process steps: winding and unwinding, developing, (descum) rinsing and drying.
FEATURES
- Excellent resolution capability, no residue of dry or wet film
- Equipped with automatic control systems to ensure longest uptime
- Single-track or double-track conveyor can be selected according to production capacity and process requirements
ADVANTAGES
- Modularized design: tension or dancer rollers can be selected according to the process requirements to avoid deforming
- Robust body structure to maintain parallel position of rollers during long term operation
- Superior Edge Position Control (EPC) to ensure an even and straight rolling
- Developing section disposes of excellent defoamer technology
- Sloped-bottom and small-volume tanks for rinsing processes to improve tank replacement rate by 50 %
