Details

Etching is a very important part in the PCM process. For instance, it needs to be considered how metals will be processed and which technical requirements are necessary according to the design and the application of the manufactured product. Furthermore, details as the type of chemicals, line speed, process time or transport system determine the advanced SCHMID etching machine layout. In addition to the etching equipment, SCHMID is also offering equipment for cleaning, developing and stripping.

High etching quality

The fine line spray manifold allows a high etching factor with smaller tolerances. Precise etching results and a uniform spraying pattern are achieved.

Option: individualized module configuration

To create an individual process sequence the etching modules can be combined with modules of the entire line system in a customized configuration.

Additional Options:

Exhaust condensor system
Drip pan
Solution transfer tank for waste water
Different systems for process control
(pH, redox, density and conductivity sensor etc.)
