Abstract:
An electronic device includes a multilevel package substrate with first and second levels extending in planes of first and second directions and spaced apart from one another along a third direction, the first level having a first side with landing areas spaced apart from one another along the first direction. The multilevel package substrate includes a conductive structure having first and second ends and conductive portions in the first and second levels that provide a conductive path along the first direction from the landing areas toward the second end, where the conductive structure includes indents that extend into the conductive portions in the first level, the indents spaced apart from one another along the first direction and positioned along the first direction between respective pairs of the landing areas.
