Hi Technetters ! Our black/brown oxide line is operating with baskets . The final sequence of black oxide process include : black oxide , cascade rinse with DI water , DMAB reducer , cascade rinse with DI water , static DI hot water , dryer . The final sequence of brown oxide process include : brown oxide , cascade rinse with DI water , , static DI hot water , dryer . We are planning to regulate DI water replenishment in flowing rinses and static hot water rinse by conductivity control . What values of conductivity should be considered ?
