Drag out is any time the chemistry is being moved when its not still in the wash process. So whether its something that in a batch machine or sitting inside a component or inline or boards too close together and the chemistry doesn’t have a place to fall back down into the chemistry tank and it starts to go into the rinse tank, we want to make sure we are controlling and containing as much as the chemistry as possible for reuse and not letting it go into other portions of the cycle.
