  • Patent number: 9930786
    Abstract: A desmear module for a horizontal galvanic or wet-chemical process line for metal, in particular copper, deposition on a substrate to be treated for a removal of precipitates comprising a desmear container connectable to a desmear unit, a pump and at least a first liquid connection element for connecting said pump with the desmear unit, wherein said pump is in conjunction with said desmear unit by said at least first liquid connection element; and wherein a treatment liquid level is provided inside the desmear module, which is above an intake area of the pump; wherein the desmear module further comprises at least a first liquid area, at least an adjacent second liquid area comprising the intake area of the pump, and at least a first separating element arranged between said at least first liquid area and said at least second liquid area.

  • Publication number: 20130164451
    Abstract: A method for depositing a coating of a first metal onto a workpiece 12 which exposes a second metal by a) providing a bath liquid 16 containing components containing ions of the first metal to be deposited, at least one complexing agent for the second metal and at least one acid, b) depositing the coating of first metal from the bath liquid 16 onto the workpiece 12, c) feeding the bath liquid 16 into a tank 18, d) cooling the bath liquid 16 in the settling tank 18 for generating a precipitate and filtrate, the precipitate comprised of the second metal and the at least one complexing agent, f) returning the filtrate to the bath liquid 16 and g) replenishing bath components to the bath liquid 16. In separating precipitate from the filtrate a pressure difference is generated by the filter.
