摘要： Provided is a method of electroplating a plastic substrate, wherein the treatment time of processes including coarsening, copper plating, nickel plating, etc. is decreased, and a semi-gloss nickel plating process (a semi-gloss nickel plating layer) in a conventional electroplating process is obviated. Also, production capacity is remarkably increased and the plating cost and use of chromium are decreased, thus lowering environmental pollution. Furthermore, the process time and the thickness of the copper and nickel plating layers are decreased, and the electroplated surface of the plastic substrate by PVD is eco-friendly and exhibits superior heat resistance, corrosion resistance, and anti-scratching and anti-oxidation properties. Moreover, as the temperature and the gas content are adjusted in the PVD process, the resulting PVD layer can show various vivid colors having a metallic and 3D appearance, and conventional monotonous color defects can be overcome.

摘要： A method of plating the connector frames includes, in part, placing the frames in a vibrating bowl to enable the bowl's vibrations load the frames in a predefined orientation onto the vibrating bowl's channel. The properly oriented frames are delivered from this channel to a track. Subsequently, a multitude of sub-racks securely engage and lift the frames from the track. The sub-racks are afterwards aggregated to form a larger rack which transports the frames to a plating tank in which the plating operation is performed. Optionally, the spacing between adjacent frames in the track is such that no contact between adjacent frames can occur. Each sub-rack has a multitude of hooks or springs adapted to engage the frames. The sub-racks may be aggregated in a horizontal direction or a vertical direction to form the larger rack.
