A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...

The majority of metal traces used to produce electrical connections in semiconductor devices begin life as blanket metal films that are later patterned and etched to create conductive connections ...
