Circudep 4000

Circudep 4000 is a highly stable and economical, graphite based direct metallization system for use with horizontal flood conveyorized process equipment. The full process sequence is comprised of three chemical stages offering a low cost and high-speed, reliable alternative to Electroless Copper. Combined with our cleaner/conditioner Circudep 3500, Circudep 4000 provides highly effective coverage for both rigid and flexible PCB applications.

Circudep 4000 and Circudep 3500 cleaner/conditioner are available in both Europe and Asia and provide the following key advantages:

  • High process yields resulting in low-cost manufacturing.
  • Shorter process cycle allowing for less equipment and reduced chemical costs.
  • Leading-edge process performance
  • Green chemistry eliminating formaldehyde and copper
