In waste printed wiring board tin lead recycling abstract: Along with the electronics industry development, the printed wiring board output and abandons the quantity to grow day by In the printed wiring board includes the massive coppers, the aluminum, the lead, the tin, the iron and so on the common metal and the ration gold, the silver, the arrowhead and so on the noble metal, as well as the few rare element selenium and so on, has the very high recycling Moreover in the line board also has very many virulent deleterious substances, like the lead, the bromine, the benzene, the mercury and so on, are an environment source of Uses the suitable recycling method, both may save the mineral resource which dries up day by day, and may reduce the heavy metal and so on the pollution, reduces to the environment the The waste line board non-pollution processing technique is the various countries key development technical This article has first carried on the brief analysis and the comparison to on at present international commonly used each processing This research experimental content including has analyzed in the waste line board through the capacity law the metal tin lead bronze content, leaches the metal in the NaCl-HCl-CuCl2 system, replaces the tin lead bronze with the aluminum sheet, and synthesizes the Key word: Waste line board; Recycling; Using craft
Tin-lead in printed circuit board waste recycling Abstract: With the development of the electronics industry, printed circuit board production and the increasing volume of Printed circuit board contains a large number of copper, aluminum, lead, tin, iron and other common metals and a certain amount of gold, silver, palladium and other precious metals, as well as a small number of rare element selenium and so on, have a high recycling In addition there are a lot of PCB toxic and harmful substances such as lead, bromine, benzene, mercury, , for environmental The use of appropriate methods of recovery will help save the increasing depletion of mineral resources, such as reducing heavy metal pollution and reduce the harm to the PCB waste treatment process is non-polluting countries in the world focused on the development of technology This article first commonly used internationally to deal with the various methods of analysis and comparison of the Experiments of this study include the capacity of law through an analysis of PCB waste in the metal tin-lead content of copper in NaCl-HCl-CuCl2 metal leaching system, replacement of aluminum with tin-lead and copper, and comprehensive
