Developing, etching, rinsing, stripping 

Development and etching of single and double sided circuit boards, stripping of circuit boards    
After the photo-technical circuit board process, the exposed circuit board is further processed in a development and etching process. This process step is supported by specially developed development and etching systems for one or two-sided printed circuit boards. The modular systems enable quick processing of circuit boards using spray etching and development processes or foam etching and continuous processes and offer the ideal conditions for a high-quality circuit board image. Special holders enable the processing of different printed circuit board materials in the manual process or in the vertical continuous process. The systems are available as floor-standing or table-top units and, in a compact design, include all process steps from development.

Foam etching and rotary developing devices
Laboratory bench systems and floor-standing devices for developing, etching and rinsing in the foam etching process and rotary development process for circuit boards and shape-etched parts are ideal small devices for laboratories, schools and institutes for creating professional sample plates and prototypes.

Spray etching and developing devices

Modular spray development and spray etching systems with rinsing device for the production of one or two-sided printed circuit boards or form-etched parts. The systems are available as manually operated or as vertical continuous systems. The new rotary spray systems result in a particularly even and intensive treatment of the entire surface.

The devices can optionally be equipped with a stripping module and dryer.
