(Summary description)The multi-layer ceramic shell brazed by Ag72Cu28 solder consists of multi-layer metallized ceramics, base and metal parts. Before entering the electroplating process, a variety of dirt, including dust, solid particles, organic matters, etc. will inevitably occur on the surface of the shell. At the same time, due to natural oxidation, there will also be a layer of oxidation. The plating surface must be cleaned before electroplating, otherwise it will affect the binding force between the coating and the substrate, resulting in peeling and foaming of the coating. Traditional removal of such pollutants, usually using toluene, acetone, ethanol and other organic solvents, but this method on the one hand is not thorough cleaning, easy to cause coating defects, on the other hand will increase production costs, causing environmental problems. Because of its uniformity, repeatability, controllability, energy saving and environmental protection, plasma cleaning machine technology has been widely used in this field. In the process of plasma cleaning machine cleaning, oxygen into plasma containing oxygen free radicals, excited oxygen molecules and particles such as electrons such plasma with a solid surface can be divided into physical reaction (ion bombardment) and chemical reaction, physical reaction mechanisms are active particle bombardment for cleaning the surface, make the discharge of pollutants from surface, chemical reaction mechanism is O active particle oxidation of organic matter into water and carbon dioxide molecules, then cleared from the surface. It is feasible to use O2 as the cleaning gas in plasma cleaning machine to deal with Ag72Cu28 solder. Before electroplating Ni and Au on the shell surface of Ag72Cu28 solder, plasma cleaning using O2 as cleaning gas can remove organic dirt, improve coating quality, which is very important for improving product quality and reliability, and also has a good demonstration effect for energy conservation and emission reduction.
