Palladium - Direct Metallization
Palladium process: similar to electroless copper, without the need of plating a copper layer.
Conditioning
Circudep DM CC 124 - is a concentrated blend of surfactants and wetting agents designed to clean the copper foil surfaces of printed circuit boards. It is an important part of the non-electroless plating process. Circudep DM CC 124 has been formulated to remove fingerprints and light oils from copper foil laminate. It contains conditioning agents which activate glass fibers and epoxy, allowing for absorption of the activator/catalyst Circudep DM CC 124 onto the surface.
Micro-etch
You may select any micro-etch from our list of Preclean and Micro-etchant solutions.
Pre-dip
Circudep DM PD 55 is an acidic-salt solution designed to improve the efficiency of the catalyst. It helps keep the concentration of some key elements optimum while improving the efficiency of the catalyst deposition on the substrates.
Activation
Circudep DM CT 60 is designed to help produce a conductive coating on non-conductive surfaces. The final surface coating can either be plated with electrolytic copper. Circudep DM CT 60 contains a special blend of acidic and organic compounds that help it increase the coating's deposit energy. The Circudep DM CT-60 solution is followed by the Circudep DM AC-170 Accelerator step. It produces the final link of the coating that produces a highly conductive surface.
Accelerator
Circudep DM AC 170 is the final step in the Direct Metallization plating process. Used after Circudep DM CT 60, Circudep DM AC 170 produces a metallic conductive coating on the surface with a significant enough thickness that allows for electrolytic plating. It has been designed to change the surface metallic complex of the Palladium/Tin coating, producing a second metallic network. Curcudep DM AC 170 changes the deposit structure and allows for both electroless and electrolytic deposition of metal.
Anti-Tarnish
Techni AT 66 contains a concentrated blend of copper oxide protection agents. It is added to the final rinse waters and will provide a temporary tarnish protection for copper. The Techni AT 66 has been formulated to remove light copper oxides and leave behind a chemically bonded anti-tarnish organic film. This clean protective surface will allow better bonding of dry film and other photo resists to the copper surface. The treated surface will prevent surface oxidation, tarnishing and staining. Techni AT 66 does not contain any chromates or waxes and can easily be removed with a mild surface etch.

Graphite Metallization Process
Our graphite process has been the "greener" choice of direct metalization for 25 years. It uses less water for rinsing with fewer chemicals than Electroless Copper. This horizontal process has been recently improved for even better performance.
Conditioning
CIRCUDEP Black Knight CC 6000 is the next-generation Alkaline Cleaner Conditioner designed for graphite. CIRCUDEP Black Knight CC 6000 has a strong conditioning action, which ensures total coverage of the exposed glass fibers and epoxy resin in the hole wall. CIRCUDEP Black Knight CC 6000 can be used in both vertical immersion and flood conveyorized process systems giving high and constant activity at low temperatures and short contact times. CIRCUDEP Black Knight CC 6000 is highly efficient when processing PTFE and other soft board substrates.
Graphite
CIRCUDEP Black Knight DM 6100 is a fine particle graphite-based direct metallization process specifically formulated for use in horizontal flood conveyor systems. This colloidal process provides conductive particles of between 0.4 and 0.8 microns that are extremely conductive and ensure complete coverage of the charged substrate ideal for subsequent Copper electroplating. Using CIRCUDEP Black Knight DM 6100 makes it possible to process high aspect ratio multilayers along with buried via and panels with small hole technologies. CIRCUDEP Black Knight DM 6100 is extremely stable and can be used constantly or with intermittent workloads, separation and sludge are eliminated due to the solution’s chemical stabilizers. CIRCUDEP Black Knight DM 6100 operates at minimal solid content giving not only a stable solution but also excellent process yields. This easy-to-control process demonstrates consistent results and ease of use, making it a real alternative to Electroless Copper.
Post-dip
CIRCUDEP Black Knight PD 6200 is the third step in the Graphite process. It is an acidic solution necessary to remove excess graphite and improves the conductivity of the coating. CIRCUDEP Black Knight PD 6200 enhances the adhesion of graphite on the hole walls and when used in a spay helps in the processing of blind and through microvias.
Micro-etch
Techni CU 85 is a heavy-duty ammonia-free peroxysulfate micro etch specifically designed to deoxidize and/or activate copper surfaces before electroplating. Techni CU 85 can also be used on Alloy 42 substrates.
Anti-Tarnish
Techni AT 66 contains a concentrated blend of copper oxide protection agents. It is added to the final rinse waters and will provide temporary tarnish protection for copper. Techni AT 66 has been formulated to remove light copper oxides and leave behind a chemically bonded anti-tarnish organic film. This clean protective surface will allow better bonding of dry film and other photo resists to the copper surface. The treated surface will prevent surface oxidation, tarnishing, and staining.
