Hi Sherry,

 

了解到有些公司用30%,有些用50%作管控,供参考。

应考虑零件的作用,可以和客户协商规定。

 

Thank you with Best Regards!

Hi Sonic

 

零件焊接后没有偏移,只是在X-RAY检验时发现有空洞现象,所以想请教一下,这类元件焊接后空洞的判定标准为多少?

 

Thanks!

Sherry

1.BGA的气泡标准不是IPC-A-610 
2.BGA的气泡标准是IPC-7095 
3.没有焊球的就不能用BGA的标准 
4.建议还是使用IPC-A-610,以零件焊接后是否偏移以及偏移的多少为判定标准 
 
Thanks and Best Regards

[TGAsia] 检验标准确认

Dear all: 
 
向各位请教一下,如图所示的零件(零件下没有焊球),像这类零件是否可以按IPC-A-610上BGA的标准来检查焊接气泡。 
  
如果不能用BGA的焊接要求来判定的话,我们应该用什么标准来判定呢?
