Voids in solder gaps are one of the main problems especially for electronics board and PCB industry.
Voids can be found in BGA solder balls, or between solder joints and BGAs, or between solder joints and PCB.
This can be caused by voids in the original solder ball, or during the reflow process.
Voids could be a cause for tilting of chip components and making cracks between chip components and solder.
Also, This is tightening the problem of not evenly distributed current or part heat and is causing stress and cracks.
