A novel low-cost and high-speed via filling method using Cu-cored solder balls was investigated for through-silicon via manufacture.Cu-cored solder balls with a total diameter of 100μm were used to fill 150μm deep,110μm wide vias in silicon.The wafer-level filling process can be completed in a few seconds,which is much faster than using the traditional electroplating process.Thermo-mechanical analysis of via filling using solder,Cu and Cu-cored solder was carried out to assess the thermo-mechanical properties of the different filling materials.It was found that the vias filled with Cu-cored solder exhibit less thermal-mechanical stresses than solder-filled vias, but more than Cu-filled vias.

轻便性  T-84C拥有一个轻巧、实用而且十分漂亮的脚架包。如果不拿脚架包,可以将T-84C直接捆绑在双肩包上,其560毫米的高度与镜头包相差无几,两者合二为一,这样背着舒服,行走起来也比较轻松。  T-84C能做到如此轻,得益于富图宝选择了昂贵的新型进口1K碳纤布做碳管原料,还得益于设计师精妙的立体镂空设计,整个脚架没有多余的噱头,体现了一切从简、实用为主的设计理念。  稳固性  磐图系列脚架均
