电子元件与覆铜基板通过焊锡粘接在一起，焊锡的去除会使电子元件与基板分离，从而分类回收。这样不仅可以提高回收效率，而且焊锡的提前分离回收为废弃印刷电路板其它金属回收创造良好的有利条件。 许多研究工作者曾采用各种机械法处理废弃印刷电路板，破碎后分选从而使金属与非金属分离。这种方法虽然简单，但在破碎过程中会产生噪音、粉尘和有害气体，给环境带来污染；且机械破碎过程耗能大、花费成本高，分离后得到的混合金属（含有焊锡）分离难度大。 [ Last edited by telomerase on 2009-1-15 at 08:29 ] |

Because electronic components and Printed circuit board (PCB) are jointed by melting solder, electronic components and PCB can be separated by the removal of melting solder, and then can be recycled separately. It will not only improve the efficiency of recycling, but also create favorable conditions for recycling other metal in PCB. A variety of mechanical treatment of were adopted by many researchers to the recycled PCB. The metal and non-metal can be separate from the broken PCB by mechanical treatment. This method is simple, but will create noise, dust and harmful gases, and pollute the environment in the process of broken. More over the energy-consuming was severe, and cost was high in this method. The separation of mixed metals (including solder) obtained from this method was very difficult. |
