Abstract: The present invention deals with the continuous metal exchange for workpieces such as a printed circuit board which can take place in a plating tank. The workpieces are conveyorized for continuous horizontal transport into and out of a plating tank. Opposite ends of the tank are provided with slots to receive and discharge the workpieces which are sealed, in the instance illustrated, by opposed rollers or an open slot of small area to prevent leakage in excess of the pump capacity. The workpieces are suspended at their upper portion by a non-conductive hanger, the lower portion of which is rendered conductive. When the workpiece enters the plating tank the conductive portion of the hanger suspending the workpiece from the conveyor, makes contact to energize bus bars thereby converting the workpiece to a cathode (or anode if metal is to be removed). A plating solution is inside of the tank and provided with anodes or cathodes energized for metal exchange. The method is directed to conveyorizing workpieces for continuous horizontal transport, sealing the opposite ends of a tank while providing for passing the workpieces through the seal at the ends of the tank, rendering the workpieces conductive while in the tank, and providing a fluid in the tank energized for metal exchange in ultimate contact with sufficient agitation (from the spargers) at the anodes and cathodes to prevent polarization during high speed plating.

Abstract translation: 本发明涉及可在电镀槽中发生的诸如印刷电路板的工件的连续金属交换。 工件被输送，用于连续水平运输进出电镀槽。 在罐的相对端设置有用于接收和排出工件的槽，在所示的情况下，通过相对的辊或小面积的开口狭缝来密封，以防止超过泵容量的泄漏。 工件通过非导电悬挂架在其上部悬挂，其下部导电。 当工件进入镀槽时，悬挂着工件的输送机的导电部分接触到母线供电，从而将工件转换成阴极（或者如果金属被去除的话）。 电镀溶液位于罐内，并设置有用于金属交换的阳极或阴极。 该方法涉及输送机工件以进行连续水平输送，密封罐的相对端，同时提供工件通过罐的端部处的密封件，使得工件在罐内导电，并且在该罐中提供流体 油箱通过金属交换，在阳极和阴极处充分搅动（来自喷雾器），以防止高速电镀过程中的极化。
