For the chemical and electrochemical final surface treatment of printed circuit boards
The COMPACTA series of devices for final surfaces and protective coatings is a universal surface treatment system for protecting PCBs.

After the etching process, the exposed copper on the circuit board would oxidise and impair the solderability of the components. For this reason, the exposed copper surfaces are coated with a final surface in one of the last production steps.
This protects the copper underneath from oxidation and thus improves the shelf life of the PCB. In addition, the final surface increases the wetability of the connection surfaces during soldering.
The available final surfaces differ in terms of their shelf life, typical areas of application and costs. However, the final surface is usually determined
by subsequent processing steps, the end product or the planned location of the end product.

The final surface treatment of the different PCB variants can be integrated into the COMPACTA device series as an additional process step or defined as a stand-alone system for final surfaces.
The special system technology combined with high-quality process chemicals guarantees an optimum surface finish for PCBs.
The system design depends on the respective process steps of the process chemistry:
End surface as an integrated system solution
e.g. direct metallization with carbon as catalyst: cleaning - catalysing (carbon) - drying - micro pickling - decapping - copper plating - final surface / protective layer - various rinsing units
Final surface as a single unit
e.g. chemical nickel/gold: cleaning – activation – chemical nickel – chemical gold – various rinsing units
