Electrolytic Etching/Deposition System. A system for continuous circuit fabrication comprising means for storing and dispensing the substrate, means for laminating the substrate, means for printing the substrate, means for optical inspection of the substrate, means for photolithography of the substrate, means for drying the substrate, means for developing the substrate, means for washing the substrate and means for electroplating the substrate.

The invention is a metal coating device in which the sheet metal fed to a coating container for being copper-coated by electrolysis in the coating container comprising a first roll device having a roll in contact with the sheet metal forwarded in the vertical position and having a rotational axis perpendicular thereto, a carrier body bearing the roll and a current transmitted via a current plate electrically connected to a power source, a coal device which includes an electric current carrying coals from the carrier body to the roll and a cooling chamber provided around the region where the current plate is connected to the carrier body and through which a cooling liquid flows.

A method for manufacturing an electroplated steel sheet by continuously performing electroplating on a steel sheet, the method including disposing a slit gas nozzle having an ejection port having a width wider than a width of the steel sheet in a width direction of the steel sheet on a side of an exit of an electroplating cell for the steel sheet to pass through, and ejecting a gas through the slit gas nozzle toward the steel sheet.

The invention provides a system for electrolytic treatment of vertically oriented substrates. The system may include an elongated bath for electrolytic liquid, a conveyor for conveying substrates to be treated electrolytically, vertically oriented and suspended from the conveyor, in a transport direction according to a horizontal transport path through an electrolytic liquid in the bath, the conveyor being arranged for clamping the substrates near a top thereof during conveyance of the substrates through the electrolytic liquid in the bath. The system may further include a number of flow devices each with at least one discharge orifice in the bath, the discharge orifices being directed in a discharge direction that extends opposite to the transport direction for creating a flow of electrolytic liquid, with a flow direction that is opposite to the transport direction, in the electrolytic liquid along at least one longitudinal side of substrates suspended from the conveyor.
