Hello,
我们单板在用LTM4643,在工厂生产的时候发现这个芯片BGA有焊接问题,切片报告显示:
1. failure的点在下图红线的那一竖排的pin1/2/3.
2. 断裂面比较平整
请问这个问题一般是什么原因导致?你们客户是否有遇到过类似的问题? 谢谢

Hi Allen,
Looks like there is a separation between the solder and PCB pads #1, #2 and #3. This could be an issue either coming from the SMT solder reflow process or PCB quality issue.
Hope this helps.
