How Hot Is My Via? (Cooler Than You Think!)
Simulations of via thermal excursions make clear designers have been overestimating what the size of a conductor must be to handle a given current. In fact, most designers don’t have any idea how hot a via gets. But it is not the current that determines the via temperature. Rather, the via temperature is determined (generally) by the conductor temperature.

Refining Lean NPI at Optimum Design Associates
The third phase of a multi-year study of the implementation of Lean NPI at a small-tier EMS reveals that moving DfM earlier in the process catches errors sooner than ever before, allowing them to be quickly and inexpensively rectified.
