Systems for producing electroplated and/or treated metal foil |
摘要 |
The present invention relates to a system and a process for producing improved quality electrodeposited and/or treated metal or metal alloy foil to be used in electrical and electronic applications. The quality of the foil being produced and/or treated by the system is improved by providing each treatment tank in the system with a dual filtration system. The dual filtration system for each tank comprises a filter conditioning loop for substantially continuously withdrawing solution from the tank and removing particulate matter from the withdrawn solution and a system for removing surface impurities from the solution. In a first embodiment, the surface impurities removing system comprises an off-line solution filtration and replenishment system. In a second embodiment, the surface impurities removing system comprises a skimmer floating on the surface of the solution. The present invention has particular utility in systems for producing electrodeposited and/or treated copper foils.
