Reliability Assessment of Reballed BGAs
In this paper, SAC305 solder balls were replaced with SnPb solder balls and tested to evaluate the reliability of these reballed components.
Program: Analysis Lab
Cleaning Reballed BGA Components
We currently clean reballed BGA components using an ultrasonic cleaner followed by baking to remove any moisture. The components appear very clean after this process. Is this an acceptable practice for cleaning reballed PGA components?
