Abstract

A water rinse system is described for use with a water jet profiler mechanism that is employed to cut printed circuit cards. The water rinse system is designed to operate immediately after cutting, while the residue is still wet and suspended in the water overspray. Deionized water at 60-80 psi is sprayed through nozzles for a period of about 8 seconds. The nozzles provide an 80-degree flat jet spray during the period that the conveyor is moving. Waste is collected in the machine's catcher tank. The cut cards are removed automatically from the water jet profiler by a stand-alone off-loader mechanism. When the conveyor stops, an off-loader removes the workboard holder and scrap. A gripping device is lowered, grips the cards and raises them about 14" above the conveyor.
