Hi Experts , While trying to solder some LGA's , we are seeing some strange issues.The XRAYS & the Die penetration test reveal the Soldering is Okay.However , the performance of the board reveals that there is a soldering issue.When we replace the LGA with another chip , the board works fine.Of course even the original LGA works fine when re soldered on some other board. I guess the XRAY & the Die penetration test cannot be 100 % conclusive regarding the Soldering quality. Is there any way to establish the soldering quality authentically.I mean to say are there any better tests ? Thanks in Advance.
