These low-cost packages can be found in many products such as laptop computers, cell phones and other portable devices.


BGA Solder Joint Vibration Fatigue

When soldered to a substrate or PCB, BGAs can reduce substrate interconnection area, complexity and cost, as well as facilitate assembly automation. However, because of a general lack of compliance in BGA solder joints, their failure in a military vibration environment becomes a serious design concern.

Continuous Improvement Approaches for Wave Soldering

If an effective process control system can be implemented with the appropriate preparation and support, most of the problems that arise in the wavesoldering process can be eliminated or at least minimized to an acceptable level.
