【摘要】 通过实验确定了各种工艺参数对包括焊膏体积在内的焊膏印刷质量的影响形式,阐述了其具体原理,并对不同焊膏体积下的0201进行组装实验,分析了焊膏量对焊点质量的影响。更多还原

【Abstract】 In this thesis,the main solder paste printing parameters are tested to get the mode that changes of parameter influence the printing quality,which include the volume of solder paste on pad. The theory of this influence is analysised. The influence of solder paste volume on solder joints’ quality is reaserched and analysied by test.更多还原
