Pumice scrubbing machine
The task of the pumice scrubbing machine is to ensure proper roughness of the production format surface before the process of the anti-solder mask application.
This is achieved by using the pumice-slurry and equally pressing the brushes which automatically adopt to the thickness of the brushed material. The last important stage of the process is the production format drying.
