I'm wondering what can we learn from an X-Ray analysis of solder joints - specifically, non-BGA joints (through-hole & SMT) joints.

Voiding, fracturing, barrel-fill, I'm sure there are some I'm missing.

Hi,

Based on our experience, you can collect X-Ray analysis of solder joints and calculate values of SPC (such as PP/PPK and GR&R). Now, you can find, based on this calculated values, if your production is good or not. Also, this helps you to detect a process problems. By the way, if you take small batch before mass production, and use SPC, you will increase your yield.

P.S. We developed system to collect and calculate values including charts. If you want more information, you can contact me by email: alexeis@proventustech.com

Best Regards, Alexei
