Summary
This paper examines the nature; the consequences and the mitigation of electrical overstress (EOS) caused by electromagnetic interference (EMI), or electrical noise, on power lines and ground in manufacturing environment.
Conclusions
High-frequency signals on power lines and ground can cause high currents into sensitive devices during soldering resulting in electrical overstress and device damage. Proper analysis of the soldering environment, as well as any environment where conductive objects come in contact with the sensitive devices and implementation of preventive and corrective measures improves yield and reduces EOS-caused failures.
