无铅工艺在塑封晶体管生产中的现状及进展

Status and Development of Unleaded Craft in the Encapsulation Transistor Production

越来越多的国家开始限制铅在人们生活中的使用。对于电气设备,无铅焊接已经成为产品出口欧盟等国家的先决条件,我国也制定了相应的应对措施。就此对无铅焊接的由来,以及在我国的实施情况进行了阐述,对无铅焊接在塑封晶体管生产中存在的问题以及应对措施进行了分析,并对我国无铅工艺的应用前景进行了描述。

More and more countries beginning limit the use of lead in people＇s life.For the electricity equipments,using unleaded to welding already becomes product export EU＇s etc.national of precondition,our country already adopts the relative measure.The cause of unleaded to welding and the implement circumstance in our country,and analysis of the existent problem of unleaded to welding in the encapsulation transistor production are discussed,meanwhile,the description to the applied foreground of our country for unleaded craft are carried out.
